Question

How much energy is needed to melt 5 g of ice? The specific latent heat of melting for water is 334000 J/kg.

Answer 1

The needed energy to melt of ice is 1670 J.

Step-by-step explanation:

Given that,

Mass of ice = 5 g

Specific latent heat = 334000 J/kg

We need to calculate the energy

Using formula of energy

`Q=mL`

Where, m = mass

L = latent heat

Put the value into the formula

`Q=5*10^(-3)*334000`

`Q=1670\ J`

Hence, The needed energy to melt of ice is 1670 J.
