MCQ Thermal Energy, Hydroelectricity, Nuclear And Non-Conventional Power Resources SET 7MCQ For Thermal Energy, Hydroelectricity, Nuclear And Non-Conventional Power Resources 1. How is thermal energy different from temperature?Thermal energy is a measure of the average kinetic energy of particles, while temperature is the total energy content of an object.Thermal energy is a measure of the total energy content of an object, while temperature is the average kinetic energy of particles.Thermal energy and temperature are the same concepts and can be used interchangeably.Thermal energy is related to mass, while temperature is related to volume.Question 1 of 152.
