Question

To heat 1g of water by 1c requires

Answer 1

Answer: B) 1 Calorie

Explanation: The heat required to raise the temperature of 1 gram of a substance by 1 degree C is known as its specific heat capacity.

Specific heat capacity of water is $\frac{4.184Joule}{g*0_C}$ and we know that, 4.184 Joule = 1 Calorie

So, specific heat capacity of water is $\frac{1Calorie}{g*0_C}$ and hence the correct choice is B.

Answer 2

C, because specific heat is measured in Joules/grams°C
