At constant pressure, what happens to the volume of a balloon if the temperature is increased?
The volume increases because the higher temperature causes atoms to move faster and this causes the walls of the balloon to expand. (This is a direct relationship) Also, the opposite is true, when the temperature on a balloon decreases, this causes the volume to decrease.Back to Top Another term for temperature is…average kinetic energy!Back to Top Boyle’s and Charles’ Law can be combined into this expression…The Combined Gas Law: P V P V 1 1 2 2 _______ = _______ T T 1 2 P = The initial pressure of a gas 1 V = The initial volume of a gas 1 T = The initial temperature of a gas 1 P = The final pressure of a gas 1 V = The final volume of a gas 1 T = The final temperature of a gas 1 Back to Top The mass of a gas or the number of atoms of a gas…remains constant.Back to Top Since the volume of a gas varies with temperature and pressure, scientists have established standard conditions known as…Standard Temperature and Pressure (A.k.a. STP): 273 K and 1 atmBack to Top The Combined Gas
