When warm air rises and cools what happens quizlet?

Warm moist air rises from the surface. As air rises, it cools. At a certain height, air cools to the dew point and condensation begins. The two factors needed are the cooling of the air and particles in the air.

How is temperature defined quizlet?

Temperature is the average kinetic energy of the molecules (how hot or cold something feels). Heat energy is the energy created y the motion of the molecules in an object.

What three things happen when air is warmed quizlet?

What three things happen when air is warmed? it rises, becomes lighter, and expands.

What happens if a rising air mass cools below its dew point temperature?

Rising air expands and cools. If the air mass cools below its dew point temperature, the air mass. – Reaches 100% relative humidity, and water vapor may condense to form clouds.

When warm air rises and cools This is an example of?

Convection currents are present in the air- A good example of convection current is the warm air that rises towards the ceiling in your house. Found inside – Page 153“When it gets as cold as the water around it, it sinks. Heat rises, cold sinks – surely you remember learning that at school?” …

What happens to warm air when it cools?

As the molecules heat and move faster, they are moving apart. 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.

How are heat and temperature related quizlet?

they are related because heat is the transfer of energy due to differences in temperature. Temperature is the measure of average kinetic energy of an atom or molecule in a substance.

How is temperature related to heat?

heat is the total energy of the motion of the molecules inside the object or particle, whereas Temperature is merely a measure of this energy. The relationship could be, the more heated an object is there higher the temperature the object will have.

What happens to air as it warms?

What happens to a layer of air when it is warmed?

What happens when lower layers of air are warmed? When lower levels of air are warmed they rise into upper atmospheres. As warm air rises, it causes wind.

What happens to the temperature of air as it rises and what happens to the temperature of air as it descends?

Warm air rises, and when it rises it becomes cooler. That information is key to understanding a lot of meteorology (science of weather). Rising air experiences a drop in temperature, even though no heat is lost to the outside.

What happens to warm air as it descends?

When you hike to the top of a mountain, the air up there has expanded to the point where it is under much lower air pressure and its temperature is much cooler as a result. As you descend, you encounter air that’s more compact (higher air pressure) and warmer as a result.

What happens to the air when it gets warmer?

Air is made up of molecules that are constantly in motion. As air warms up, the molecules start to vibrate and bump into each other, increasing the space around each molecule. Because each molecule uses more space for motion, the air expands and becomes less dense (lighter).

What happens when the air becomes warm?

What does warm air always do?

When air heats up and expands, its density also decreases. The warmer, less dense air effectively floats on top of the colder, denser air below it.

What is it called when warm air rises?

Convection. When a fluid such as air or water touches a hot object, it can heat up and then move in bulk as a fluid, thereby carrying the heat quickly to new locations. Hot air rising is a common example of heat convection.

How does heat affect temperature?

When a system absorbs or loses heat, the average kinetic energy of the molecules will change. Thus, heat transfer results in a change in the system’s temperature as long as the system is not undergoing a phase change.

What does temperature depend on?

Temperature depends on energy and mass The same quantity of energy, shared out amongst less mass, gives a bigger temperature rise.

Why does warm rise?

Hot air rises because when you heat air (or any other gas for that matter), it expands. When the air expands, it becomes less dense than the air around it. The less dense hot air then floats in the more dense cold air much like wood floats on water because wood is less dense than water.

How does temperature change in each layer of the atmosphere?

Temperature increases as you gain altitude in the stratosphere and the thermosphere. Temperature decreases as you gain altitude in the troposphere and mesosphere. Air temperature varies in complicated ways with altitude.
