Item EG026003: For two glasses containing the same amount of milk, the glass of milk with the higher temperature has more thermal energy than the glass of milk with the lower temperature.
A student has two identical glasses of milk except that the temperature of the milk in one glass is 40ºF and the temperature of the milk in the other glass is 80ºF.
The milk at which temperature has more thermal energy?
- The milk at 40ºF has more thermal energy.
- The milk at 80ºF has more thermal energy.
- Both the milk at 40ºF and the milk at 80ºF have the same amount of thermal energy.
- Neither the milk at 40ºF nor the milk at 80ºF has any thermal energy.

- PS3.A Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present.
- NRC Framework
- PS3.A Thermal energy is the random motion of particles (whether vibrations in solid matter or molecules or free motion in a gas)...
