Question

The specific heat capacity of water is ___________.

• A. $1cal{g}^{-1}{}^{o}C^{-1}$
• B. $4186J{g}^{-1}{}^{o}C^{-1}$
• C. $4186kJk{g}^{-1}{K}^{-1}$
• D. All of the above.

Answer 1

The correct option is A

$1cal{g}^{-1}{}^{o}C^{-1}$

Specific heat capacity:

1. The quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree is called the specific heat capacity.
2. The specific heat capacity of water is $1cal{g}^{-1}{}^{o}C^{-1}$.

Hence, option (A) is the correct answer.
