Question

1) What is echo?

2) What is kinetic energy?

3) How can we transfer heat?

4) What is conduction?

5) What is convection? ​

Answer 1

Answer:

1)a sound or sounds caused by the reflection of sound waves from a surface back to the listener.

2)energy which a body possesses by virtue of being in motion

3)Heat is transfered via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation). Heat is usually transfered in a combination of these three types and seldomly occurs on its own.

4)the process by which heat or electricity is directly transmitted through the material of a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.

*the process by which sound waves travel through a medium.

*the transmission of impulses along nerves

5)the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
