Describe an experiment to show that heat causes change in the state of a body.

Boiling water

Explanation:

A simple experiment that can be done to show that heat causes change in the state of a body is boiling water.

In fact, take a pot and fill it water. Then place the pot on the stove burner and turn it on: heat will be given to the water inside the pot. After a while, you will notice that the water in the pot will start boiling. Eventually, all the water will disappear, converted into steam.

This is an example of change of state, in particular from liquid state (water) into gas state (steam). The changes of state are:

Melting (from solid to liquid)

Boiling (from liquid to gas)

Condensation (from gas to liquid)

Freezing (from liquid to solid)

Sublimation (from solid to gas)

Deposition (from gas to solid)

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
