Item EG084002: For two glasses containing water at the same temperature, the glass with more water has more thermal energy than the glass with less water.
A student has two identical glasses that have different amounts of water in them. Glass 1 has more water in it than Glass 2.
If the temperature of the water in the glasses is the same, how does the thermal energy of Glass 1 compare to the thermal energy of Glass 2?
- Glass 1 has more thermal energy than Glass 2.
- Glass 1 has less thermal energy than Glass 2.
- Glass 1 has the same amount of thermal energy as Glass 2.
- Neither glass of water has any thermal energy.

- Disciplinary Core Ideas
- 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
- Thermal energy is the random motion of particles (whether vibrations in solid matter or molecules or free motion in a gas)...
