When a solid is placed in a container and heat is applied, a phase change occurs. Watch the video and identify which of the foll

owing statements are correct. Check all that apply. View Available Hint(s) Check all that apply. The temperature increases while all of a liquid is converted to a gas. The average kinetic energy of the system changes while all of a solid is converted to a liquid. Temperature remains constant while all of a solid is converted to a liquid. When heat is applied to a solid, the molecular motion decreases as the temperature increases. When a solid is converted to a liquid, heat is absorbed.

Explanation:

Phase change is said to occur when a substance from one state of matter changes to another state. Phase change occurs at a fixed  temperature. For example, water boils and converts to steam at 100°C. During the phase change, the average kinetic energy of the system  remains constant which is indicated by constant temperature. Actually, the molecular motion does increase with increase in heat but heat is absorbed in breaking the bonds and formation of new bonds.

Thus, third and last statement are correct.

Answer:

a) false b) true c) true d) false and e) true

Explanation:

a) false.   All the energy applied is used for the phase change, so the temperature remains constant.

b)   true.   The kinetic energy is associated with the speed of the particles and they have more mobility in the liquid, therefore, more kinetic energy.

c)   true.   Since energy is used for state change

d)  false.   In general, mobility and temperature are proportional

e)  true.  Heat is the source of energy for the change of state

Alex777 [14]
<span>the statement that is true regarding flexibility is : b. a joint's range of motion will be lost if the joint is not used regularly. Our body is like a machine. If we not constantly heat it up, our body will be more prone to injury. We can see that the old people who lived within the tribe in the middle of the mountain are far stronger than the one who lived in the city.</span>
