The block is made of A) Tin, as its specific heat capacity is
Explanation:
When an amount of energy Q is supplied to a sample of material of mass m, the temperature of the material increases by , according to the following equation
:
where is the specific heat capacity of the material.
In this problem, we have:
m = 2 kg = 2000 g is the mass of the unknown material
is the amount of energy supplied to the block
is the change in temperature of the material
Solving the equation for , we can find the specific heat capacity of the unknown sample:
And by comparing with tabular values, we can find that this value is approximately the specific heat capacity of tin.
