Question

the amount of heat required to raise the temperature of a body from 20℃ to 60℃ is (water equivalent of body is 10 gm).

Answer 1

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

hope this would help you

Answer 2

Answer:

400 cal

Explanation:

specific heat of water in teRMS of cal is 1

so ms∆t = 10*1*(60-20)

=10*1*40

=400cal.
