Answer :

Eduard22slygo Eduard22slygo

The amount of heat energy lost by the 100 mL of water when it all freezes is 33400 J

Data obtained from the question

Volume of water = 100 mL

Heat (Q) =?

How to determine mass of water

Volume of water = 100 mL
Density of water = 1 g/mL

Mass of water =?

Mass = Density ×Volume

Mass of water = 1 × 100

Mass of water = 100 g

How to determine the heat

Mass of water = 100 g
Heat of fusion (ΔHf) = 334 J/g

Heat (Q) =?

Q = m × ΔHf

Q = 100 × 334

Q = 33400 J
