Explanation:
The amount of thermal energy Q supplied to a substance is related to the increase in temperature of the substance, , according to the equation
where:
m is the mass of the substance
is the specific heat capacity of the substance
In this problem, we have:
m = 1.2 kg is the mass of the block
is the amount of energy supplied to the block
is the specific heat capacity of the block
Solving for , we find the increase in temperature:
And since the initial temperature was
The final temperature will be
