If ice is warmed and becomes a liquid, which type of process is it?
exothermic
spontaneous
combustion
endothermic

Option (d) is the correct answer.

Explanation:

A reaction in which heat is absorbed by the substance or reactant molecules is known as an endothermic reaction. In this process energy of reactants is less than the energy of products.

Whereas a reaction in which heat is released by the substance or reactant molecules is known as an exothermic reaction. In this process energy of reactants is more than the energy of products.

For example, when ice is warmed then heat is absorbed by ice molecules due to which there occurs decrease in its intermolecular forces. As a result, ice changes into water.

Therefore, we can conclude that if ice is warmed and becomes a liquid, then it is an endothermic process.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
