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.
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.
<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>
<span>C. switching to cheaper fuel. Physical capital pertains to non-human asset. Under this type were the asset that use to process goods and services like machinery, buildings etc.</span>
