energy needed for 1kg of substance to change state with no temp change
1 of 6
What does SLH of fusion mean?
Energy to change 1kg of substance from solid to liquid with no temp change
2 of 6
What does SLH of vaporisation mean?
Energy to change 1kg of substance from liquid to gas with no temp change
3 of 6
Energy change for change of state(J) = ...
SLH x mass(kg)

Calculate energy needed to covert 0.5kg of ice to water. SLH of fusion of water = 334,000
0.5 x 334000 = 167,000 J = 167 KJ
