An increase in temperature will cause an increase in volume, while a decrease in temperature will cause a decrease in volume.

## Related Questions  High temperature makes the volume greater. As the temperature of a gas increases, so does the volume. Yes. An increase in temperature will cause an increase in volume, while a decrease in temperature will cause a decrease in volume. Yes it does affect, the denser the substance is, the lesser the temperature needed for it to be frozen . Hence . Density of a substance is indirectly propotional to the temperature it needs to be frozen.  No, the quantity doesn't affect the temperature but it may (and usually does) affect the time taken for a substance to achieve that temperature. Density is equal to the mass of the substance divided by the volume of the substance. D=m/V When you heat a gas, it expands. When it expands, its volume increases. If the volume of a substance increases while the mass stays the same (no loss nor gain in mass) then the density will decrease. If the gas cools, the volume will decrease and the density will increase.   Generally, heat added to materials causes an increase in volume as well as temperature. If the volume is contained (as with gases), the temperature increases the pressure. Yes. The boiling point is independent of volume. Volume can affect how long it takes for a substance to reach boiling point. The particle size,temperature and agitation affect the rate at which a substance will disolve in a solution.   As a general rule, increasing the temperature will increase the volume of a liquid (or a solid or a gas) the higher the temperature, the higher the volume of a solid - michelle strafer Yes, it does affect the volume. The relationship between them can be explained by the equation pV=nRT (pressure x volume = number of moles of gas x molar gas constant x temperature). Therefore, there is a direct proportionality between temperature and volume. If the temperature doubles, so does the volume. The law that describes the relationship between volume and temperature is "Charles's Law", which states that as the temperature of a substance increases, the volume also increases. An increase in temperature usually results in an increase in volume. If you think about a pan of water (say 1 quart) and heat it until it boils, it will turn to steam which will easily fill the whole room - a few cubic yards. Factors which affect the amount of energy needed to change the temperature of a substance are: 1) the amount (mass) of the substance 2) what temperature change is required (from what temperature to what temperature) 3) the specific heat of the substance, which is "the number of calories required to raise the temperature of 1 gram of the substance by 1 degree Centigrade" 4) the ambient temperature of the surroundings where this change is to be carried out  Volume is a measure of how much space something takes up. Temperature and pressure affect volume. Yes, the size (volume and mass) and the type of the cup will affect its temperature The amount of a substance that a liquid holds will be the solubility of that substance in that volume of the liquid - at that temperature.
