What happen to the volume of the air as it is heated?
The air expands.
When a balloon is heated and its volume double what happen to its density?
It is reduced by haft
What are examples of matter changing volume but not changing the mass?
When air is heated, that volume of air expands (which is why hot air balloons go up). The hot air has changed in volume, but it is still the same mass.
What will happen to those balloons if you take them outside on a cold day?
When you cool a gas at a constant presure, the volume of the gas decreases. Therefore, the balloons will slightly shrink.
When fluids expand when they are heated does their density increase?
No. Remember that density is a ratio of mass compared to volume. If the volume increases without adding more mass, then the density would decrease. This is why hot air balloons rise.
Did any change happen to the shape and the volume of a balloon when air was blown into it?
The balloons shape changed and went through an outward distortion. The volume of the balloon expanded as air was blown into it.
Does the volume of an object change if heated?
The volume of a substance increases when heated
Will the volume of metal decrease if it is heated?
No, the volume of a metal increases as it is heated. It expands.
Is hot air balloons filled with helium?
No, it is filled with heated air.
Does gas expand when heated?
Yes. Typically, a gas will approximately expand according to the ideal gas law; this means that if you double the temperature (expressed in kelvin), and keep the temperature constant, the volume will approximately double.
How does the volume and density of a substance change when it is heated?
The volume of a substance increases when heated, causing a decrease in density.
When a liquid is heated how does its volume change?
When a gas is heated, its' volume increases.
