Question

calculate the specific latent heat of fusion of a solid if 25gm of it requires 8400J of heat energy for melting.


pliz explain the answer...​

Answer 1

Given :

1. Mass = 25gm,
2. Energy = 8400J.

　

To find : Calculate the specific latent heat of fusion of a solid.

　

Calculations :

→ 8400/25

→ 336

　

→ 336 (1000)

→ 3.36 × 10^5 J/kg

　

Therefore, 3.36 × 10^5 J/kg is the specific latent heat.
