If it is cooled its gets extremely cold from the helium,and when the heat is in the balloon it keeps it warm when its in the helium
When iodine crystals are heated and cooled in a hot water bath what happens?
When iodine crystals are heated, they sublimate directly from solid to gas without melting. As the hot iodine gas cools, it reverts back to solid form on the cooler surfaces of the container, forming iodine crystals again. This process is called sublimation.

egg comes out of it
What happens when rock heated?

What might cause convections in a hot springs?
Most hot springs are heated from below and cooled by the air above. This tends to make the top of a spring cooler than the bottom. As a result the air-cooled water winks while the newly warmed water rises.
What would happen to a magnet if heated?
Heating a magnet can weaken or even destroy its magnetic properties. This is because increased temperature can disrupt the alignment of the magnetic domains within the magnet, causing it to lose its magnetization.
What happen with the air in a soccer ball with a cooled and heated?
The air pressure goes down when cooled, goes up when heated. A soccer ball left outdoors in freezing weather does not have much bounce. Left outside on a hot day, has a lot of bounce.
What is operation process for hot plate with magnetic stirrer?
This particular hot plate is a common piece of laboratory equipment used for mixing solutions in the laboratory. It has a slow spinning magnetic field generated in the hot plate and this spins a plastic coated magnet placed inside the solution being heated. Turn the hot plate on, place the beaker with the solution on the hot plate. Place the magnet in the solution, adjust the temperature and speed of the magnet with dials on the front of the hot plate. This hot plate does not get hot enough usually for cooking.
What happens when a used dry cell graphite rod is heated?
