Question

Which of the following is a valid unit for specific heat?

Answer 1

Answer:

The answer is D

Explanation:

Answer 2

Answer: Option (d) is the correct answer.

Explanation:

When a substance is heated and the heat used to raise its temperature by a unit mass of the given amount is known as specific heat of the substance.

Mathematically,    $Q = mC\Delta T$

where              Q = heat added in calories or joules

                        m = mass of substance in grams or kg

                        C = specific heat

               $\Delta T$ = change in temperature

Thus,  $c = \frac{cal}{g^{o}C}$

Hence, we can conclude that a valid unit for specific heat is ca$cal/g^{o}C$.
