60.) Gasoline engines and diesel engines are… A.) insulators B.) external combustion engine C.) heat engine D.) heat mover
61.) A device that heats your home by removing thermal energy from one location and transferring it to another location at a different temperature is a(n)… A.) conductor B.) internal combustion engine C.) heat engine D.) heat mover
62.) A device that converts thermal energy into mechanical energy is a… A.) conductor B.) refrigerator C.) heat engine D.) heat mover
I need to know if these are true or false and if they are false what goes in the place of the all caps words.?
1.The transfer of thermal energy by conduction and convection DOES NOT require matter
2.The transfer of thermal energy by radiation DOES NOT require matter
3.A material that allows heat to pass through it easily is and INSULATOR
4.Insulation rated R-35 allows MORE heat to pass through it than insulation rated R-1
5Solar collectors are used in PASSIVE solar heating systems
6A solar heating system that does not use fans or electrical devices is AN ACTIVE solar heating system
7A steam engine is an example of an INTERNAL combustion engine
8.The fuel of an external combustion engine is burned OUTSIDE the engine
9.A STEAM-HEATING system uses radiators to transfer thermal energy
10.Refrigerators and air conditioners are HEAT PUMPS
11Steam-heating systems require MORE water than hot-water systems
12cause dark colors REFLECT more radiant energy than light colors, solar collectors are usually painted black
13Many external combustion engines are TURBINES to produce mechanical energy
