Question

Calculate required heat energy to exchange 10gm of water from 30°c to40°c

Answer 1

Answer:

Mass of water = 10g

Initial temperature = 30°C

Final temperature = 40°C

We have to find heat required to increase temperature...

Specific heat capacity of substance is defined as the heat required to increase temperature of 1g substance by 1°C.

Q = m × c × ΔT

SHC of water = 1 cal/g °C

⇒ Q = m × c × ΔT

⇒ Q = 10 × 1 × (40-30)

⇒ Q = 10 × 10

⇒ Q = 100 cal :D
