The specific latent heat of fusion (when solid change to liquid) of ice is the amount of heat required to change 1 kg of ice to water without a change in temperature. The specific latent heat of fusion of ice is 0.336 MJ per kg..
till class tenth level,
A difference between endothermic and exothermic involves reactions in the environment. An endothermic reaction takes place when energy is absorbed from surroundings in the form of heat, and exothermic is when energy is released from the system into the surroundings.
so look for heat exchange. like when ice will convert to water, it will need heat.

@nukita-puyol Then A should be the answer of this question.But answer is C.The process l,ll and lll are endothermic since they absorb heat energy and process IV,V and Vl are exothermic since they release energy then why answer is C.

@Eliza-Berthman See option 3
Like You'll give heat to water vapour and it'll convert to ice !! Wrong right .
