No. air actually contracts as it gets colder, while air expands as it gets warmer. For example, lightning is so hot, it causes the air to heat up intensly. This rise in temperature causes the air to expand so fast, that it breaks the sound barrier. This causes a sonic boom, and that is the thunder that you hear after lightning strikes.

What is thermo cycling?

Thermo cycling AKA thermic cycling AKA thermal cycling means taking something, heating it, cooling it and heating it and cooling it over and over again. Each hot-cold sequence will introduce mechanical stresses as materials expand on heating and contract on cooling. It's often used to research how durable a certain design is likely to be.


How does air pressure affect air movement?

Air pressure affects air movement because air moves from high pressure to low pressure. The air pressure pushes or will press the air around.


Why is your compressor icy?

Probably the system is overcharged - too much refrigerant. Liquid refrigerant is boiling off as it enters the compressor inlet making it very cold. This can harm the compressor since liquid refrigerant is not compressable. It can also happen if the evaporator coil is blocked or plugged up with debris (on the air side).


What is the stream behind a jet called?

The condensate or "con" trail. There can be two sources. Water is a significant component of efficient fossil fuel combustion. When this hot water (essentially dry steam) exits the plane's engine it cools and condenses into small water droplets that look like long straight clouds. Also, moisture in the air flowing around the wing tip can compress and expand again, showing up as a thin streak of cloud.

Do car tires expand in the summer?

Yes, the heat causes the air to expand in the tires. Conversely, the cold air in winter reduces tire pressure.


What happens to the water molecules when the air above gets cold?

the water molecules get cold and expand and turn into ice


Why does water expand when cold?

Water expands when it is cold because the water molecules found in water expand in the cold.


How does air expand in closed objects?

cool Actually, when there is warm air, like in a balloon it will expand. When you go outside, the balloon will shrink if it is cold outside. When you go back into the warm indoors, the balloon will go back to its normal size.


Why car tires expand on hot days?

Everything expands when it gets hot, contracts when cold including air molecules...tires expand just from the heat of driving down the road as well


What role does an evaporator coil perform?

The evaporator coil places a big role in your home's air supply. When the coils expand, cold air pumps through the coils, traveling into the system to keep a hot/cold balance in the home.


What is the scientific law of expand and contrast?

Expand- Hot Contrast- Cold


What are some of the effects of heat on air?

Heat causes a gas (like air) to expand. If the gas is in a closed container, the pressure will increase instead. Hot air also rises because it is lighter than cold air.


Is thunder the sound of warm air colliding with cold air?

You are wrong. Thunder is the noise made when the lightning causes the air to heat up and expand suddenly. When this explodes we hear the sound we call thunder.

What is the difference between hot air particles and cold air?

The difference lies in the speed of particles, not in the composition or structure of the individual particles themselves. Temperature measures the average speed of particles, so the particles which compose hot air are going to be moving faster than the cold air particles. Because of this, the two take on new properties - hot air will expand more rapidly and rise, while cold air will sink.
