Question

Which of the following statements is true? Entropy has the unit of (A) Heat (B) Work (C) Energy (D) Heat capacity (E) Temperature

Answer 1

D) Heat capacity

Step-by-step explanation:

Entropy is defined as

`dS = (dQ)/(T)`

Where

dS: is an infinitesimal amount of entropy

dQ: is an infinitesimal amount of heat

T: is the temperature in absolute units

The units of this are units of heat over units of temperature.

This is the same unit used by heat capacity

`[(J)/(K)]`

Do not confuse it with the specific heat capacity. Heat capacity is a property of a body and is an extensive property, while specific heat capacity (sometimes shortened to specific heat) is a property of material and is an intensive property.
