The latent heat of fusion for metal is 246kj per kg. How much heat would be used by melting 10 tonnes of metal?
To calculate the amount of heat used in melting 10 tonnes of metal, we need to use the equation:
Heat (Q) = Mass (m) × Latent Heat of Fusion (L)
Given:
Mass (m) = 10 tonnes = 10,000 kg
Latent Heat of Fusion (L) = 246 kJ/kg
Substituting these values into the equation:
Q = 10,000 kg × 246 kJ/kg
Now, let's calculate the heat used:
Q = 2,460,000 kJ
Therefore, the amount of heat used in melting 10 tonnes of metal is 2,460,000 kJ.
