Thermal Energy
Kinetic Energy
Particle Energy
the average kinetic energy of the particles in iced tea is —————than the average kinetic energy of the particles in hot tea.
louder
Prettier
Higher
Lower
Thermal Energy depends upon the energy of the particles as well as the number of particles.
Which would have more thermal energy, a small cube of Ice at zero Celsius or a large cube of ice at zero Celsius?
The large ice cube because it has more particles than the small ice cube
