Question

What is the amount of heat required to raise temperature of water from 20°C to 50°C Mass of water is 100g and latent heat is 4.18 joule /gram​

Answer 1

Explanation:

Hello

$\huge\underline{\underline{\sf ANSWER}}$

Given that :

Mass = 100g

Latent heat = 4.18 J/g

∆t = 50-20 = 30

Q = mc∆t

= 100×4.18×30

= 12540J

So amount of heat required to raise temperature of water from 20°C to 50°C is 12540J
