Answer:
17.41°C is the change in temperature of the aluminum block.
Explanation:
Latent heat of fusion water = 334 J/g
Heat required to freeze 1 gram of water = -334 J
Heat required to freeze 2.58 grams of water = Q
Heat lost by water will be equal to heat gained by the aluminum block
Formula used to calculate heat absorbed by substance:
Where:
Q = heat absorbed by substance
c = specific heat of substance
m = Mass of the substance
ΔT = change in temperature of the substance
We have :
Mass of aluminum block= m= 55 g
Heat capacity of aluminum = c = 0.9 J/g°C
Change in temperature of the aluminum block= ΔT = ?
Heat absorbed by the aluminum = Q'
17.41°C is the change in temperature of the aluminum block.
