Answer 2

Answer:

A constant volume air thermometer works on Gay Lussac's law​ and Charles law.

Explanation:

• This thermometer works under the condition when the temperature of a gas increases, the volume also increases. Using Charles law , the temperature can be measured by the volume of gas at a certain temperature by using the formula. This works on the same principle as mercury thermometers.

                                         $V is directly proportional to T\\V/T=Constant\\V=kT\\T = T is the temperature.\\V=the volume.\\k= constant for the system.$

• The relationship between temperature and volume, at a constant number of moles and pressure, is called Charles and Gay-Lussac's Law studied this relationship. Charles did the original work, which was verified by Gay-Lussac.
• They observed that if the pressure is held constant, the volume V is equal to a constant times the temperature T.
