Physics question . Need help?
Are this questions true or false
1.) All objects radiate energy.
2.) A good emitter of heat is also a good reflector of heat.

4.) An ice skater skates on a thin film of water between the blades and the ice.
5.) When ice changes to water at 0 decrease Celsius, energy is released.
6.) The process of boiling actually cools the water.
1. False. some absorb energy.
2. True. When it is already emitting heat,any heat incident on it will bounce back
3. False. I think cooling will not be so much to freeze the water.
