Two students design an experiment to find the specific latent heat of fusion of ice.
They set up their equipment as shown in the diagram:
The students also have access to a power supply, a voltmeter, an ammeter, a stop-clock, and a top-pan balance.
a.[6]
- Explain how the students could use this equipment to determine an accurate value for the specific latent heat of fusion of ice.
b.[3]
In their experiment, the students find that 220 g of ice takes 73.7 kJ of energy to change state.
Calculate the specific latent heat of fusion of ice based on their results.
