Question

How much energy is released or obsorbedwhen 1gm of water at 0°cfreezes to ice at 0°.

Answer 1

Answer:

no energy is released because the energy is used to change the state of matter [ from liquid to gas ].

This type of heat is called latent heat.

Answer 2

Dear Student,

As water freezes to ice, energy would be released by the system.

◆ Answer -

Energy released = 334.4 J

● Explaination -

Moles of water in 1 g are -

Moles = given mass / molar mass

Moles = 1/18 mol

As we know, enthalpy of fusion for water is 6.02 kJ/mol.

Hence, energy released by the system is -

Energy released = enthalpy of fusion × moles

Energy released = 6.02 × 1/18

Energy released = 0.3344 kJ

Energy released = 334.4 J

Hope that helps you...
