Question 5

When ice is warmed to 32°F, the heat needed to convert the ice into water without raising the temperature of the water is called _____ heat.
A)latent
B)polymorphous
C)thermoscopic
D)ambient

Accepted Answer

The heat needed to convert ice into water at the same temperature (32°F) without changing the temperature is called latent heat. This is the heat required for a phase change, in this case, from solid to liquid, without a temperature change.

Question 17

Technician A says kinetic energy in the crankshaft is converted into electrical energy by the generator. Technician B says electrical energy in the generator is converted into chemical energy in the battery. Who is correct?
A)A only
B)B only
C)both A and B
D)neither A nor B

Accepted Answer

Both statements are correct. The generator (alternator) converts mechanical energy from the crankshaft into electrical energy, and this electrical energy is then used to charge the battery, converting it into chemical energy stored within the battery.
