A family was vacationing in the mountains in a cabin that had no electrical power. They needed boiling water in order to prepare dried soup mix.
With no electrical energy available, which method would most likely provide enough thermal energy to quickly heat the water to boiling?
Using a microwave oven to heat water in a glass jar for 3 minutes
Shaking the water in a closed, insulated plastic bottle for 3 minutes
Shining a battery-powered flashlight on a metal container of water for 10 minutes
Placing a metal pot of water over glowing charcoal in an outdoor grill for 10 minutes

When you are cold, rubbing your hands together very quickly can warm them up. Why does this happen?
Thermal energy is converted to electricity.
Mechanical energy is converted to thermal energy.
Mechanical energy is converted to sound.
Electrical energy is converted to mechanical.
An astronaut on the Moon picks up a stone and throws it hard against another stone. He doesn't hear any sound. Why not?
Human ears do not work on the Moon.
There is no air on the Moon, and the sound cannot travel.
Rocks are not as hard on the Moon.
The atmosphere on the Moon is too cold for sound.
