usually in hot or warm temperatures because, hot air expands and cold does not.
I think it will last longer in a warm air because we blow balloons and we have warm air so I think is the warm air.
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.
Cold Front
The best material to make socks out of to keep feet warm in cold weather is wool. Wool is very thick and that makes it possible for it to hold in the body heat and keep the cold out.
No. The volume of the helium will change as it expands the balloon due to the increase in temperature. The density of an element never changes. The reason for that is because density is just a fancy way of saying 'The atoms are this far apart' in the equation mass/volume = density.
when it is cold the cremaster muscle contracts and draws the testes closer to the body to keep them warm.
Warm air and warm water. Cold air and cold water keep ice cooler longer.
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
Things which keep warm things warm and cold things cold are referred to as insulators.
Warm:)
Cold water doesn't burst at all.
Cold air is denser than warm air, therefore a balloon filled with cold air will weigh more than an identically sized balloon full of warm air. This extra weight causes the balloon to sink bellow warmer air. Cold air is denser than warm because as molecules become cooler they move more slowly causing them to be closer together.
Cats have fur to keep them warm when they are cold.
They get cold as they lose the ability to keep warm, and die.
To insulate : To keep warm things warm and cold things cold
