Question

how much calorie is the amount of heat required to raise the temperature of 20 gram of water by 20 degree Celsius ​

Answer 1

Answer:

Explanation:mass of the body is equal to 10 grams

initial temperature of the body is equal to 20 degree Celsius

final temperature of the body= 60 degree Celsius

specific heat capacity of water is equal to 1 calorie per gram degree Celsius

then, heart required = mass x specific heat capacity x change in temperature

= 10 x 1 x (60 - 20)

= 10 x 40 = 400 cal
