That's false. Outer space is empty, or nearly so. The air at sea level still has a density of about 1.2 kilogram per cubic meter. Much less than typical solid or liquid matter, but not quite empty either.
False. Mechanical waves require a medium, such as air or water, to travel through. They cannot propagate through empty space because they rely on the vibration of particles in the medium to transfer energy.
No, air is composed of various gases such as nitrogen, oxygen, and carbon dioxide, while empty space refers to the absence of matter. Air occupies space and has mass, while empty space does not have these properties.
vacuum
A vacuum is empty space with no air. It is a region where the pressure is significantly lower than atmospheric pressure, resulting in the absence of air or any other gas molecules.
Venus
False. Mechanical waves require a medium, such as air or water, to travel through. They cannot propagate through empty space because they rely on the vibration of particles in the medium to transfer energy.
In empty space, ie in a vacuum
No, air is composed of various gases such as nitrogen, oxygen, and carbon dioxide, while empty space refers to the absence of matter. Air occupies space and has mass, while empty space does not have these properties.
False. Air resistance is friction. A meteor coming in from space hits our atmosphere and glows brightly due to the airs friction.
vacuum
True. In a forced-air heating system, warm air is circulated through the space using a fan or blower, which creates airflow and distributes the heat through convection. The warm air rises and displaces cooler air, creating a cycle that helps to evenly heat the space.
Yes. Vibrations can travel through anything except space where there is a vacuum.
It's a high-pressure zone with rising air. true or false
true
No air
A vacuum is empty space with no air. It is a region where the pressure is significantly lower than atmospheric pressure, resulting in the absence of air or any other gas molecules.
