A system consists of a gas contined in a thin ballon. If the ballon deflates as the temperature of the gas changes from `90^(@)C "to"25^(@)C`, then:

Is the temperature of an isolated system of gas be changed ?

If the pressure of a gas at constant volume changes from 2 atm to 1 atm. The temperature changes from 0^@C

175 calories of heat is reuired to raise the temperature of 5 mol of an ideal gas at constant pressure from 20^@ C to 25 ^@ C the amount of heat required to raise the temperature of same gas from 20^@ C to 25^@ C at constant volume will be

A gas sample in a flexible container is maintained at constant pressure while its temperature is increased from 25^(@)C to 75^(@)C . If the initial volume of the gas is 4.2L, what is the change in volume due to the temperature increase?

A cylinder contains a gas at temperature of 27^(0)C and a pressure 1MPa . If the temperature of the gas is lowered to -23^(0)C , the change in pressure is
