What is more dense a cool or a hot object?
A cool object is generally more dense than a hot object. As a hot object heats up, its particles have more energy and move around more, causing the object to expand and become less dense. On the other hand, a cool object's particles have less energy and are more closely packed together, making it more dense.
Does a hot or cold object give off more radiation?
A hot object gives off more radiation than a cold object. The amount of radiation emitted by an object is directly related to its temperature, according to the Stefan-Boltzmann law. The hotter an object is, the more energy it emits as radiation.
At the same pressure which is more more dense- hot air or cold air?
Cold air. At the same pressure, the VOLUME of a gas will be proportional to the absolute temperature - that is, to temperature expressed in Kelvin. Density is inversely proportional to volume.
What term describes how hot or cold an object is?
What term describes how hot or cold an object is?
What makes an object hot or cold?
An object is hot or cold based on its temperature, which is a measure of the average kinetic energy of its particles. When particles move faster, they generate more heat, making the object feel hot. Conversely, when particles move slower, less heat is produced, causing the object to feel cold.

What does cold air have more than hot air?
Cold air is more dense than hot air. This is because gas expands when it is heated.

Is hot water less dense than cold water?
Yes, because the higher the temperature, the faster and more spread out the molecules, therefore making hot water less dense than cold water.
Does a hot or cold object weigh more?
wow what a question!! well i don't know but hot air rises so cold would probably weigh more..

Why does cold water in a tube sink to the bottom of room temperature water?
Cold water is dense and cold water sinks, just like air, cold air falls and hot air rises.
What is the difference in hot and cold air particles?
Hot air particles have more energy and move more quickly compared to cold air particles, which have less energy and move more slowly. This results in hot air being less dense and rising, while cold air is denser and sinks.
What has more resistance hot air or cold air?
Cold air is more dense, thus is gives more resistance. Notice how you land when you're flying. In the winter, it's usually a smooth gradual landing. In summer, you hit the runway with much more force.
Is hot air denser than cold air?
No, hot air is less dense than cold air.
