When water is cooled the molecules are moving around less (have less kinetic energy). This means strong hydrogen bonds start to form between the slightly more electron dense oxygen on one molecule and the slightly less electron dense hydrogen on another molecule. This bonds push the molecules further apart than just weak Van der Waals' forces in water so the ice expands

If a bottle is filled with hot air and then put in a freezer why will the bottle change volume and shape?

When the hot air inside the bottle cools down in the freezer, it will contract and decrease in volume. This decrease in volume causes the pressure inside the bottle to decrease, leading to a change in its shape. The bottle may collapse or deform as a result of the reduced pressure.


Can you keep a ice cube from melting?

You can prevent an ice cube from melting quickly by keeping it in a well-insulated container, placing it in a cooler with ice packs or dry ice, or storing it in a freezer. Limiting its exposure to warmer temperatures and minimizing air circulation around it can also help slow down the melting process.


Can you put a chest freezer next to a radiator?

It is not recommended to put a chest freezer next to a radiator as the heat from the radiator can affect the freezer's performance. The increased temperature can cause the freezer to work harder to maintain its cool temperature, leading to higher energy consumption and potential damage to the freezer. It is best to place the chest freezer in a cool and well-ventilated area away from heat sources.


What happens when you put a bottle of water in the freezer?

As the water in the bottle freezes and turns into ice, it expands. This expansion can cause the bottle to deform or even burst. It's generally not recommended to freeze a bottle of water, especially if it's a plastic bottle.


What will happen if you put a ice on a glassfull of water?

The ice will float, partly above the surface of the water but mostly under it. As time goes on, the ice will become smaller. Eventually, the ice will completely disappear, and the temperature of the water will be lower than it was before the ice was put into it.
