How much heat energy is required to raise the temperature of 0.368 kg of copper from 23.0 ∘c to 60.0 ∘c? the specific heat of copper is 0.0920 cal/(g⋅∘c) .

1252.67 calories or 1.25Kcal

Explanation:

From

H= mcθ

m= mass of the body

c= specific heat capacity of the body

θ= change in temperature

m= 0.368K= 368g

c= 0.0920

θ= 60°C-23°C= 37°C

H= 368× 0.0920× 37

H= 1252.67 calories or 1.25Kcal

d.) circle motion requires a force to give it a centripetal acceleration.
