Question

How do you calculate the heat of fusion △Hf of ice?
Mass of empty cup: 4.6 g
Mass of cup + heated water: 77.6 g
Starting temperature of the water: 57.1 c
Final temperature of ice/water mixture: 0.9 c
Mass of cup + cool water: 130.6

Answer 1

Answer:

please mark me the Brainliest answer

Calculate the heat of fusion of ice from the following data of ice at

added to water. Mass of calorimeter

, mass of calorimeter

water

, <br> mass of calorimeter

water

ice

, initial temperature of water

, final temperature of the mixture

. The specific heat of calorimeter

. Assume that the calorimeter was also at

C initially

Text Solution

Solution :

Mass of water

<br> mass of ice

<br> Heat lost by water

heat gained by ice to melt

heat gained by (water obtained from melting of ice

calorimeter) to reach

<br>

<br> (where L is the latent heat of fusion ice) <br>

Key Takeaways: Heat of Fusion for Melting Ice

Heat of fusion is the amount of energy in the form of heat needed to change the state of matter from a solid to a liquid (melting.)

The formula to calculate heat of fusion is: q = m·ΔHf
