When air rapidly expands its temperature normally _?
When air rapidly expands its temperature normally _?
When air rapidly expands, its temperature normally _______. decreases. You just studied 29 terms!
What happens to the volume of air as it rises what happens to its temperature?
AS the air rises it expands so the volume of air increases. As the air expands its temperature falls.
Why does the direction of coastal winds change?
Why does the direction of coastal winds change from day to night? It changes because the temperature of the water changes. in the day, the warm air in the land rises and needs the cooler air from the water to replace it. Whereas at night, the water is warmer and needs cooler air from the land.
In which direction does heat flow spontaneously between hot and cold objects?
Heat is the transfer of thermal energy from one object to another because of a temperature difference. Heat flows spontaneously from hot objects to cold objects.
Why do gases expand when heated and contract when cooled?
Gases also expand when they are heated and contract when they are cooled. The molecules of a hot gas move faster than the molecules of a cold gas, so they hit each other harder and bounce harder off the sides of a container. This makes the molecules move farther apart and push the sides of a container outward.
What happens to the volume of air as it rises what happens to its temperature quizlet?
What happens to its temperature? AS the air rises, it expands, so the volume of air increases. As the air expands, its temperature falls.
What happens when air expands?
So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward. This is the concept used in the hot air balloons.
Why does air expand as expands?
A rising parcel of air expands because the air pressure falls with elevation. This expansion causes the air to cool. A falling parcel of air contracts because the air pressure increases.
What causes coastal winds?
Coastal Winds stem from large storm systems moving onshore that can pack quite a punch. Often these storms move inland, knocking over power lines and leaving residents in the dark for days. Homes and businesses may be damaged when a strong storm moves onshore.
Why does wind direction change during the day and night near seaside?
Answer and Explanation: The direction of coastal winds changes from day to night. This is due to the differential heating of land and ocean.
What is the direction of flow of hot air?
And unless people interfere, thermal energy — or heat — naturally flows in one direction only: from hot toward cold. Heat moves naturally by any of three means. The processes are known as conduction, convection and radiation. Sometimes more than one may occur at the same time.
Why do substance expand when their temperature is increased?
Substances expand when their temperature increases because the molecules have more energy and move faster and farther apart.
