State the meaning correctlY- Degree of hotnessName the physical quantity correctly- Latent heat offusionExptain the concept correctly in beaker A- Heat is used to break the bonds between ice molecules //

weaken the forces of attraction between molecules- Kinetic energy of the ice molecules remains unchangedExplain the concept correctly in beaker B- Heat is used to increase the kinetic energy of the water molecules- Temperature depends on kinetic energyState the specific heat capacity with the heat correctly- Substance with higher specific heat capacity requires more heat to
