Is water boiling in a pot endothermic or exothermic? Endothermic means that there is more energy needed to keep it going than it produces. Since boiling water needs a source that heats it and the boiling will automatically stop once the source is removed, it is an endothermic process. it is endothermic..since the water is boiling,it has latent heat of vaporisation. this means that some amount of heat is being absorbed by the water to convert water into water vapour.

Is Vaporization Exothermic or Endothermic? Exothermic and endothermic reactions both cause some type of energy level differences. In an exothermic reaction, energy is released in the form of heat. As chemical bonds are formed, energy is released. An example is water turning into ice. Chemical bonds form and release energy to create ice crystals. An endothermic reaction, however, is the opposite. Here, the energy is absorbed in the form of heat. When a chemical bond is broken, the energy used creates an endothermic reaction. Changing ice into water, then vapor, requires the chemical bonds to be broken.

Explaining Why Condensation Is Exothermic Molecules in Motion. Condensation is an exothermic process, but in contrast to a bonfire, condensation is not so obviously exothermic because it does not release heat in a way that is easy to sense or observe. Objects in motion have kinetic energy related to this motion, and water molecules are no exception.

Endothermic and Exothermic Reactions Endothermic reactions cannot occur spontaneously. Work must be done in order to get these reactions to occur. When endothermic reactions absorb energy, a temperature drop is measured during the reaction.Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+δH).ndothermic reactions cannot occur spontaneously. Work must be done in order to get these reactions to occur. When endothermic reactions absorb energy, a temperature drop is measured during the reaction.

Understanding Endothermic Reactions So, in this endothermic example, the temperature of the ice and water stayed the same at the exact instant of the reaction. As long as heat continues to be applied after the change from ice to water, either from our burner flame, or even just from sitting in a warm room, the temperature of the water goes up.

- Boiling point of water is inversely proportional to atmospheric pressure, which depends on altitude and weather. Higher altitude, lower boiling point. Water boils at 100 C …at sea level. Go below sea level (ocean level) to the Dead Sea and the boiling point will actually be greater than 100 C.

- Endothermic and Exothermic Processes. Exothermic-the word describes a process that releases energy in the form of heat. Forming a chemical bond releases energy and therefore is an exothermic process. Exothermic reactions usually feel hot because it is giving heat to you. Endothermic-a process or reaction that absorbs energy in the form of heat. Breaking a chemical bond requires energy and therefore is Endothermic. Endothermic reactions usually feel cold because it is taking heat away from you.

Evaporation of water is which type of process?endothermic or exothermic?how? Report Abuse. Endothermic because it takes heat (or energy) to change from liquid to vapor. for any material vapor have always higher energy than its liquid state so it needs energy to go in vapor phase that's why it is endothermic. satyanand_sh · 8 years ago.

Endothermic Definition Endothermic Definition: within heating from the Greek prefix endo-, meaning “inside” and the Greek suffix –thermic, meaning “to heat”. The term endothermic describes a process which absorbs thermal (heat) energy.

- What processes are endothermic? A: Endothermic, or heat-absorbing, processes include melting ice cubes, evaporating liquid water, melting solid salts, cooking an egg, baking bread, separating ion pairs and splitting a gas molecule. Other examples include forming a cation from an atom in the gas phase and making anhydrous salt from a hydrate.

Endothermic solid-solid reactions Description. In this demonstration you can observe an endothermic reaction. Solid hydrated barium hydroxide is mixed with solid ammonium chloride in a beaker. The liquid produced evolves ammonia gas and the temperature drops dramatically to about -20 °C. In this demonstration you can observe an endothermic reaction.

Boiling The sensitivity of different micro-organisms to heat varies, but if water is held at 70 °C (158 °F) for ten minutes, many organisms are killed, but some are more resistant to heat and require one minute at the boiling point of water. Boiling is also used in cooking.

- Is vaporisation an exothermic or endothermic process? Any reaction categories into exothermic and endothermic based upon change in enthalpy of reaction. If difference in enthalpy of product and reactant comes positive value then …it is termed as endothermic and if it is negative value then exothermic reaction.

Endothermic process The term endothermic process describes a process or reaction in which the system absorbs energy from its surroundings; usually, but not always, in the form of heat. The intended sense is that of a reaction that depends on absorbing heat if it is to proceed.

Boiling point The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.The boiling point of a liquid varies depending upon the surrounding environmental pressure.he boiling point corresponds to the temperature at which the vapor pressure of the liquid equals the surrounding environmental pressure. Thus, the boiling point is dependent on the pressure.

Endothermic and exothermic? Exothermic refers to a reaction that produces heat. When you balance the equation the energy released when new bonds are formed is greater than the energy use when bonds are b … roken.  An endothermic reaction takes in heat as it requires more energy to break its bonds than it has from the bonds it creates.

Which of the following processes is exothermic? Best Answer: Formation of dew is condensation. There is more energy in water vapor than in water liquid. Therefore, as dew is formed, energy is given off, an exothermic reaction. It is not vaporization because you have to add energy to water to get steam, the cold pack is definitely endothermic.Source(s): science teacher · 7 years ago.herefore, as dew is formed, energy is given off, an exothermic reaction.

Exothermic reaction An exothermic reaction is a chemical or physical reaction that releases heat. It gives net energy to its surroundings. That is, the energy needed to initiate the reaction is less than the energy that is subsequently released.

Endothermic and Exothermic Reactions If heat is given off, the reaction is exothermic. Exothermic means that during the reaction, molecules have moved from a higher state of energy to a lower state. An endothermic reaction is the opposite. This is when a reaction starts colder and ends up hotter, taking in energy from start to finish.hat is an example of an exothermic reaction. Exothermic reactions give off heat. At the molecular level, an exothermic reaction is when a bond is formed. When two things come together, they're happier and take less energy to stay together.

Is water boiling in a pot endothermic or exothermic? Best Answer: Exothermicc means that there is more energy going that coming in, so it can sustain itself. Endothermic means that there is more energy needed to keep it going than it produces. Since boiling water needs a source that heats it and the boiling will automatically stop once the source is removed, it is an endothermic process. Source(s): Hockey · 6 years ago.
