1) What is the specific latent heat of fusion of water?
Specific latent heat of fusion is the amount of heat absorbed or released by a substance when changing states. This could be boiling or melting. Latent heat of fusion is the amount of energy needed to melt a substance, while latent heat of vaporisation is the amount of energy needed to boil a substance. The specific latent heat of fusion of water is 334 j/g
In the graph, you can see that as the temperature increases more energy is needed to heat the water. When the temperature hits the latent heat of fusion, the temperature stops rising as the energy is being used to change the state of water. This also happens when the latent heat of vaporisation

2) What is

paper towels
Stopwatch to measure time in minutes and seconds

Method
1) Pour 200cm3 of water into 4 same sized beakers of the same materials. This is so the materials does not affect the in temperature
2) I’m going to measure the temperature of the water. I’m going to make sure the temperature is the same to make it a fair test. I’m going to leave the water to become room temperature for about 5 minutes
3) I’m going to add 15g of ice to Beaker 1, 25g to Beaker 2, 25g to Beaker 3 and the fourth Beaker will have no ice. The fourth beaker will set
