The mass of the water in the original container by assuming that all heat lost by the copper is gained by the water is 116.23 g.
Mass is the term that told the quantity of a matter.
Given the mass of copper = 110g
The specific heat capacity of copper is 0.20 j/C g
The initial temperature of copper is 82.4 C
The final temperature of copper and water is 24.9 C
Now, we would determine the mass of the water.
From the formula for sensible heat, ΔH = m × c × ΔT
Where, H = sensed heat,
m = mass,
ΔT = temperature change
Putting the above values in the equation.
ΔH = m × c × ΔT
110 × 0.20 × ( 82.4 - 24.9 ) = mw × 4.186 × (24.9 - 22.3)
1265 J = mw × 10.8836 or mw = 116.23 g
Thus, the mass of water is 116.23 g.
