Liquids "expand" when heated and "contract" when cooled.
The ideal gas law applies to liquids as well as gasses:
where p is the absolute pressure of the gas; V is the volume; n is the amount of substance; R is the universal gas constant; and T is the absolute temperature.
In SI units, p is measured in pascals; V in cubic metres; n in moles; and T in kelvin. R has the value 8.314472 J·K−1·mol−1 in SI units[4]).
Given that the liquid is in an open container, the pressure of the gas/liquid p becomes a constant in the above equation and the volume V varies directly with the temperature T.
Some may think that water "expands" when it becomes ice in violation of the above law, but the actual expansion is secondary to the trapped air bubbles inside the structure of the ice, and not actually in the frozen water itself.
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.
When the temperature of a substance is increased, its molecules or atoms jiggle faster and move farther apart, on the average. The result is an expansion of the substance. With a few exceptions, all forms of matter--solids, liquids, gases, and plasmas--generally expand when they are heated and contract when they are cooled.
no
Matter expands when it is heated.

Liquids expand when heated and contractwhen cooled.
Liquids expand when heated and contract when cooled.
No, gasses expand when heated and contract when cooled.
Oil does expand when heated and contracts when cooled.
Yes, in general a liquid will expand when heated. They contract when they are cooled.
No, metals always expand when heated and contract only when cooled.
I assume your question deals with expansion in volume under conditions of heating and / or cooling. I believe that most liquids expand in volume when they are heated and contract in volume when they are cooled. Water does not follow this pattern entirely - it expands when it is cooled from a liquid state to a solid state.
Metals contract when they are cooled, and expand when they are heated.
yes
When a gas is heated up, the particles within the gas start to move faster, going farther apart (expansion). When a gas is cooled, the particles slow down and it starts to condense (contract), and if cooled enough, into a liquid.
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.
The bar will contract (get shorter) as it cools down, and expand (get longer) as it is heated up.
