What else can I help you with?
Do any matter expand when cooled and contract when heated?
Sort of. In the temperature range of 0-4 Degrees Celsius water contracts when heated and expands when cooled. Outside of this temperature range it behaves normally.
Do particles get smaller or bigger when heated?
When particles are heated or cooled, they do not change size at all. They simply move with greater kinetic energy so the space between particles increases. This prompts the changes in size we see when substances are heated or cooled.
What happen to air when heated it will move up or down?
When air is heated, it becomes less dense and therefore lighter than the surrounding cooler air. This lighter, warm air will rise because of the buoyant force. Conversely, when air is cooled, it becomes denser and therefore heavier, causing it to sink.
What will happen to a stone if heated it for a long time and cooling it instantly?
If a stone is heated for a long time and then cooled instantly, it may crack or shatter due to thermal stress. The rapid change in temperature can cause uneven expansion and contraction within the stone, leading to structural failure.
What is the difference about the behaviour of water when it is heated or cooled?
When water is heated, it absorbs energy and its temperature rises, eventually reaching its boiling point where it turns into steam. When water is cooled, it releases energy and its temperature drops, eventually reaching its freezing point where it turns into ice.
What changes take when water is heated or cooled?

What is the opposite of heated?
The opposite of heated is cooled.
Does plastic need to be heated or cooled to make it set?
Cooled to set
Can gold be heated and cooled?
Yes
Liquids contract when heated?
Liquids expand when heated and contractwhen cooled.
Does gases contract when heated?
No, gasses expand when heated and contract when cooled.
Do liquides contract when heated?
Liquids expand when heated and contract when cooled.
Can you put heated milk back in the fridge after it has cooled down?
Yes, you can put heated milk back in the fridge after it has cooled down.
Why is tar heated and not cooled before applied to a roof?
Tar is heated so it can stick to what ever it is going on. If it was cooled it would not stick right.
Oil expand or contract when heated?
Oil does expand when heated and contracts when cooled.
Do liquids have fixed temperature?
No. They can be heated or cooled.
