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 to melt 10 tonnes of metal, we will need to convert the mass from tonnes to kilograms.
1 tonne is equal to 1000 kilograms.
Therefore, 10 tonnes is equal to 10 * 1000 = 10,000 kilograms.
Next, we can use the formula to calculate the heat used:
Heat used = Latent heat of fusion * Mass
Given that the latent heat of fusion for the metal is 246 kJ per kg and the mass is 10,000 kilograms, we can substitute these values into the formula:
Heat used = 246 kJ/kg * 10,000 kg
Now we can calculate the answer:
Heat used = 246,000 kJ per tonne * 10 tonnes
Heat used = 2,460,000 kJ
Therefore, 10 tonnes of metal would require 2,460,000 kJ of heat to melt.
