True or false for the following question
1.Thermal conductivity is a measure of how thermal energy is transferred through a solid by combined contribution of electron conduction and atom vibration (phonon) transmission.
2.Heat capacity is a measure of the ability of the material to absorb thermal energy.
3.Thermal expansion of a material (how its shape changes with temperature) can be measured using a constant called the linear coefficient of thermal expansion.
