Part 3: True or False 5pts.

Question

___ Heat always moves from a colder object to a warmer object.
___ Heat can be transferred through space by radiation.
___ Metals are good conductors of heat.
___ A blanket keeps you warm because it produces heat.
___ Warm air rises, and cold air sinks.

Answer 1

Here are the true or false answers for each statement:

1. Heat always moves from a colder object to a warmer object. - False

   • Heat naturally moves from warmer objects to colder ones.

2. Heat can be transferred through space by radiation. - True

   • Heat can be transferred through electromagnetic waves, which is how radiation works.

3. Metals are good conductors of heat. - True

   • Metals typically have high thermal conductivity, making them good conductors of heat.

4. A blanket keeps you warm because it produces heat. - False

   • A blanket does not produce heat; it insulates your body and traps the heat that your body generates.

5. Warm air rises, and cold air sinks. - True

   • This is a basic principle of convection; warm air is less dense and rises, while colder air is denser and sinks.

So, the answers are:

1. False
2. True
3. True
4. False
5. True
