Question

Heat capacity of a substance is infinite. It means :

• A. heat is given out
• B. heat is taken in
• C. no change in temperature whether heat is taken in or given out
• D. all of the above

Answer 1

The correct option is C no change in temperature whether heat is taken in or given out

The heat capacity is the amount of heat required to raise the temperature of an object or substance by one degree.

$\Delta Q=n{C}_p\Delta T$

So, $\Delta T=\frac{\Delta Q}{n{C}_p}$

If heat capacity i.e. $C_p$ is infinite, $\Delta T$ is negligible.
