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.
Yes, lead does expand when heated and contract when cooled, just like most materials. This property is known as thermal expansion and contraction.
Yes, gases can both expand and contract. When heated, gases expand as the molecules move more rapidly, increasing the pressure and volume. Conversely, when cooled, gases contract as the molecules slow down, decreasing the pressure and volume.
Most materials expand when heated due to increased molecular motion, and contract when cooled due to decreased molecular motion. Examples include gases, liquids, and solids such as metals and plastics.
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 coefficient of _____ expansion. It depends what kind of expansion you are talking about.
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.
No, metals always expand when heated and contract only when cooled.
Yes, most liquids expand when heated because the heat causes the molecules within the liquid to move faster and spread out, increasing the overall volume. However, there are exceptions such as water, which expands when heated until it reaches a temperature of 4 degrees Celsius, at which point it begins to contract.
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.
The bar will contract (get shorter) as it cools down, and expand (get longer) as it is heated up.
