The thermometric property of a constant volume thermometer is?
Answer Details
A constant volume thermometer is a type of thermometer that measures temperature by keeping the volume of the gas inside the thermometer constant. The thermometric property in this case would be the property that changes with temperature and is responsible for indicating the temperature on the thermometer. In the case of a constant volume thermometer, the thermometric property is the pressure of the gas. As the temperature increases, the average kinetic energy of the gas molecules increases, which in turn causes them to collide with the walls of the thermometer more frequently and with greater force. This results in an increase in the pressure of the gas, which is measured by the thermometer and used to indicate the temperature. Therefore, the correct option is "change in pressure."
