# Question: a In a constant volume gas thermometer if the pressure

(a) In a constant volume gas thermometer, if the pressure of the gas decreases, has the temperature of the gas (1) increased, (2) decreased, or (3) remained the same? Why?

(b) The initial absolute pressure of a gas is 1000 Pa at room temperature (20 oC). If the pressure increases to 1500 Pa, what is the new Celsius temperature?
