WebAssertion The specific heat of a gas in an adiabatic process is zero but it is infinite in an isothermal process. Reason Specific heat of a gas is directly proportional to heat … WebThe temperature, pressure, and volume of the resulting gas-air mixture are 20 ° C, 1.00 × 10 5 N/m 2, and 240 cm 3, respectively. The mixture is then compressed adiabatically to a volume of 40 cm 3. Note that in the actual operation of an automobile engine, the compression is not quasi-static, although we are making that assumption here.
