Responses
A PlasmaPlasma
B Energy
C Pressure
D Temperature
The correct answer is B - Energy.
When energy is added or removed from a substance, it can cause a change in the state of matter. The three common states of matter are solid, liquid, and gas. When energy is added to a substance, the particles within it gain more energy and move faster, which can cause a change from a solid to a liquid (melting) or from a liquid to a gas (evaporation). This is because the increased energy breaks the bonds between the particles, allowing them to move more freely.
On the other hand, when energy is removed from a substance, the particles lose energy and slow down. This can cause a change from a gas to a liquid (condensation) or from a liquid to a solid (freezing). As the energy is reduced, the particles come closer together and form bonds, resulting in a change of state.
It's important to note that there is also a state of matter called plasma, which is the fourth state. Plasma occurs at very high temperatures and consists of ionized gas, where the atoms have lost their electrons. However, the addition or removal of energy is not the primary factor that causes a substance to enter the plasma state.
