Calculate energy required to heat water

WebAs the calculation shows, when 1 liter of water is heated to a temperature of 95 ° C and it is cooled to 70 ° C, 25 kcal of heat will be released (1 calorie is the amount of heat required to heat 1 g of water per 1 ° C). Water leakage during depressurization of the heating system will not have a negative impact on health and well-being. WebJul 4, 2016 · For water, the enthalpy of fusion is given as. #DeltaH_f = "333.55 J g"^(-1)# The trick here is to realize that the amount of heat needed to melt ice will be equal to the amount of heat given off when liquid water freezes. You can thus say that when #"1 g"# of water freezes at #0^@"C"#, #"333.55 J"# of heat are being given off to the surroundings.
