States of halogens at room temperatures? Because of the greater temporary dipoles, bromine molecules are stickier than chlorine molecules. Chlorine molecules will break away from each other at much lower temperatures than bromine molecules - hence bromine is a liquid and chlorine is a gas at room temperature. This is the reason that (all other things being equal) bigger molecules have higher boiling points than small ones.

Why is pentane a liquid at room temperature? Best Answer: intermolecular forces of attraction such as van der Waal's increase with increasing molecular weight. this increases things like boilling point, which affects the point at which a substance will exist as gas or liquid or solid.

- Oxygen can indeed be a gas and it is a gas at room temperature,  which is why we are able to breathe it. When its temperature is  lowered a great deal, it can be a liquid or…, if the temperature is  lowered further, it can be a solid (like ice).

What are the gas elements at room temperature? The noble gases are; Helium, Neon, Argon, Krypton, Xenon, and Radon. Radon is toxic, as it is radioactive. The other elements that are gases at room temperature are: fluorine, F2; chlorine, Cl2; oxygen, O2; nitrogen, N2; and hydrogen, H2. All these gases are diatomic.

Is iodine a solid a liquid or gas? Why is Chlorine a gas Bromine a liquid and Iodine a solid at room temperature? Van der waals forces are present in all three chlorine, bromine and iodine, however the strength of the van der waals forces depend on the number of electrons. The more electr…ons present, the stronger the van der waals forces.

Carbon dioxide Although carbon dioxide mainly consists in the gaseous form, it also has a solid and a liquid form. It can only be solid when temperatures are below -78 o C. Liquid carbon dioxide mainly exists when carbon dioxide is dissolved in water.Carbon dioxide is only water-soluble, when pressure is maintained.oseph Black, a Scottish chemist and physician, first identified carbon dioxide in the 1750s. At room temperatures (20-25 o C), carbon dioxide is an odourless, colourless gas, which is faintly acidic and non-flammable. Carbon dioxide is a molecule with the molecular formula CO 2.

- 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.

Why are oils liquid at room temperature? trans fat molecules can stack more easily (like saturated fats) and have higher melting points, so are more likely to be solid at room temperature (like margarine). the more unsaturated a fat is, the more disoraganized the molecules are (they don't stack easily). they have lower melting points and are more likely to be liquid at room temperature. this is the case for oils.

- Most metals are good conductors of heat and they are solids at room temperature. Mercury is the only one in liquid state at room temperature, and has high coefficient of expansion. Hence, the slightest change in temperature is notable when it's used in a thermometer. This is the reason behind mercury and alcohol being used in thermometer.

- The boiling point at standard pressure is around −34 ˚C, but it liquefies at room temperature at 740 kPa (107 psi). Elemental chlorine is yellow-green, but the chloride ion, in common with other halide ions, has no color in either minerals or solutions (example, table salt).

CH 105 - Chemistry and Society N2 and NaCl, each with 2 atoms (or ions) -. Obviously, N2 exists as a gas at room temperature while NaCl is a solid. Clearly, the IMF's between molecules of NaCl in a crystals of NaCl are much stronger than for N2. Liquid nitrogen exist, but boils at a temperature of -196oC. The difference can be explained by viewing a model of the crystal structure of NaCl.

What is the only non metal which is a liquid at room temperature?? Report Abuse. Gallium (31Ga) is the only metal, except for mercury, caesium, and rubidium, which can be liquid near room temperatures; this makes possible its use in high-temperature thermometers. It has one of the longest liquid ranges of any metal and has a low vapour pressure even at high temperatures.

- The reason why nitrogen gas is inert at room temperature is because the triple bond between the two nitrogen atoms in each nitrogen molecule (N2) is very strong, and therefore … it takes a lot of energy to break that bond, and until that bond is broken, the nitrogen cannot react with any other chemical.

Freons Thus, CHClF 2 is Freon 22; CCl 2 F 2 is Freon 12; CCl 3 F is Freon 11 (the zero, for the number of carbons, does not show); C 2 Cl 2 F 4 is Freon 114; and Freon 113 is C 2 Cl 3 F 3 . Freons are essentially colorless, odorless, nonflammable, and nontoxic. Their low boiling points, low surface tension, low viscosity, insolubility in water, and general chemical inertness are quite remarkable: They remain stable in hot concentrated mineral acids and are unaffected by molten sodium.
