- Boyle's Law (P = 1/v) Gases can be compressed because most of the volume of a gas is empty space. If we compress a gas without changing its temperature, the average kinetic energy of the gas particles stays the same. There is no change in the speed with which the particles move, but the container is smaller.

- Temperature is a number that is related to the average kinetic energy of the molecules of a substance. If temperature is measured in Kelvin degrees, then this number is directly proportional to the average kinetic energy of the molecules.Heat is a measurement of the total energy in a substance.That total energy is made up of not only of the kinetic energies of the molecules of the substance, but total energy is also made up of the potential energies of the molecules. So, temperature is not energy.hat energy can be used to increase the kinetic energy of the molecules, which would cause an increase in temperature. Or that heat could be used to increase the potential energy of the molecules causing a change in state that is not accompanied by an increase in temperature. back.

- One way to think of this is if you increase the speed of the molecules –by increasing their temperature-the force of the molecules hitting their container increases and this increases the pressure.This relationship is called Gay-Lussac’s Law and makes up part of the ideal gas law.ne way to think of this is if you increase the speed of the molecules –by increasing their temperature-the force of the molecules hitting their container increases and this increases the pressure.

- The kinetic energy and molecule velocity increase with temperature. The mass of the molecule is m and the velocity is v. . New bonds can form only if the atoms are close enough together to share electrons. The collisions need to be violent (energetic) enough to break bonds in the reactant molecules.

Kinetic theory of gases The kinetic theory describes a gas as a large number of submicroscopic particles (atoms or molecules), all of which are in constant, random motion. The rapidly moving particles constantly collide with each other and with the walls of the container.Kinetic theory explains macroscopic properties of gases, such as pressure, temperature, viscosity, thermal conductivity, and volume, by considering their molecular composition and motion.he temperature of an ideal monatomic gas is proportional to the average kinetic energy of its atoms. The size of helium atoms relative to their spacing is shown to scale under 1950 atmospheres of pressure. The atoms have a certain, average speed, slowed down here two trillion fold from room temperature.

Thermometers as Speedometers It is at this point that we can use a more sophisticated definition of temperature. Temperature is a measure of the average kinetic energy of the particles within a sample of matter. In a previous unit of The Physics Classroom Tutorial, kinetic energy was defined as the energy of motion. An object ... or a particle ... that is moving has kinetic energy. There are three common forms of kinetic energy - vibrational kinetic energy, rotational kinetic energy and translational kinetic energy. Up to this point of the Tutorial, we have associated kinetic energy with the movement of an object (or particle) from one location to another.

What Effect Does Kinetic Energy Have as It Relates to the Diffusion Rate? Temperature directly influences the kinetic energy -- or energy of motion -- of the molecules in a fluid. The higher the temperature, the higher the kinetic energy and motion of the molecules. When heat energy is added to a system, the molecular kinetic energy increases and the molecules begin to move more quickly. Since they are moving more quickly, the chance of collision with each other and with the sides of the container increases.

- Its definitely C because PV=nRT, when T doubles, the Volume has to double, so that makes B wrong. A is wrong because temperature is what drives the kinetic energy of liquids/gases. And since A is wrong, D is wrong because more kinetic energy would drive the particles to hit the walls with greater force. most definitely move faster. nelle · 3 months ago.

What is the relationship between thermal energy, temperature and kinetic energy? Best Answer: When temperature increases, particles in an object speed up, which means an increase in thermal energy. Since the particles are moving more now, the potential energy decreases, therefore kinetic energy increases.

- We know from experience that substances are solids at lower temperatures and liquids and gases at higher temperatures. This accords with our definition of temperature as average kinetic energy: since the molecules in gases and liquids have more freedom of movement, they have a higher average velocity.

- they posses Kinetic energy when collide with surface with the same energy.The collective energy is measured as pressure. Explanation: when molecules of gas or air move they possess certain amount of kinetic energy,by colliding any surface the collective energy the exerts on the surface is measured as pressure . And that is how these molecules cause pressure.

- For most substances, a gas has the highest kinetic energy Substances transform to a solid, liquid or gas because of either temperature or pressure changes. Every substance has different properties. Generally speaking, whenever the temperature is increased, molecules start moving more quickly and farther apart. At one point, different for each substance, the solid substance will have accumulated enough energy to break the intermolecular bonds and become a liquid, and so forth. As the substance changes from solid to liquid to gas, the molecules move with less velocity, hence, less kinetic energy. Pressure changes also can affect a phase change. If more pressure is applied, molecules will move closer together. If compressed enough, the substance will change into a more compact phase.
