The statement is: "$A$ system cannot possess mechanical energy but possesses work." Correct this statement to make it $\text{TRUE}$.

Discuss the modes (or methods) for changing the internal energy of any system.

Given are statements for certain thermodynamic variables:
$(A)$ Internal energy,volume $(V)$ and mass $(M)$ are extensive variables.
$(B)$ Pressure $(P)$,temperature $(T)$ and density $(\rho)$ are intensive variables.
$(C)$ Volume $(V)$,temperature $(T)$ and density $(\rho)$ are intensive variables.
$(D)$ Mass $(M)$,temperature $(T)$ and internal energy are extensive variables.
Choose the correct answer from the points given below:

Explain the concept of temperature based on the Zeroth Law of Thermodynamics.

What is thermodynamics?

Temperature is a measurement of the coldness or hotness of an object. This definition is based on:
