Question

To heat 1g of water by 1c requires

A. 1 Volt

B. 1 Calorie

C. 1 Joule

D. 1 Watt

Answer 1

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

Answer 2

Answer: B) 1 Calorie

Step-by-step 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
`(4.184Joule)/(g*0_C)` and we know that, 4.184 Joule = 1 Calorie

So, specific heat capacity of water is
`(1Calorie)/(g*0_C)` and hence the correct choice is B.
