If the two temperatures on Fahrenheit scale differ by $54^\circ\text{F}$, then the difference in temperature on the Celsius scale is

A gas at normal temperature is suddenly compressed to one-fourth of its original volume. If $\gamma = 1.5$, then the increase in the temperature of the gas in Kelvin is ($\gamma$ is the ratio of specific heats)

The thermodynamic process in which no work is done by the gas or on the gas is

The kinetic energy of an ideal gas is $E_0$ at $27^\circ\text{C}$. When the temperature is increased to $177^\circ\text{C}$, then kinetic energy will be
