The heat capacity of our mystery metal is <u>b) one-third as great</u>
<h3>Further explanation
</h3>
The law of conservation of energy can be applied to heat changes, i.e. the heat received / absorbed is the same as the heat released
Q in = Q out
Heat can be calculated using the formula:
<h3>Q = mc∆T
</h3>
the mass of the metal is the same as that of the water
so m water = m metal
the heat energy used to heat water and metals is the same, so
Q water = Q metal

m = metal
w = water
T = the final temperature of the mixture
Tm = metal temperature
Tw = water temperature
so the equation becomes:
