heat is added to it?
The mass of the water is 41.9 g
Explanation:
When an amount of energy Q is supplied to a sample of substance of mass m, the temperature of the substance increases by , according to the equation:
where:
m is the mass of the substance
is the specific heat capacity of the substance
is the change in temperature
In this problem, we have:
Q = 525 J is the amount of heat supplied to the water
is the change in temperature of the water
is the specific heat capacity of the water
Solving for m, we find the mass of the water:
