What else can I help you with?
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.
What happen to the volume of the air as it is heated?
As air is heated, its volume typically expands. This happens because the heat increases the kinetic energy of the air molecules, causing them to move faster and spread out, which in turn leads to an increase in volume.
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.
How many balloons fit in a garbage bag?
The number of balloons that can fit in a garbage bag depends on the size of the balloons and the size of the garbage bag. To calculate the maximum number of balloons that can fit, you would need to measure the volume of a single balloon and the volume of the garbage bag, then divide the volume of the garbage bag by the volume of a single balloon. This would give you an estimate of the maximum number of balloons that can fit in the garbage bag.
What are hot air balloons filled with?
It is simply air that has been heated. Hence the namehot air balloons are filled with hot air from a propane tank
What is the increase in volume of a material when heated called?
The increase in volume of a material when heated is called thermal expansion.
Why do hot air balloons float in the ar?
As the air in the balloon is heated, it expands and becomes less dense, or that is, becomes lighter. This then provides lift to the balloon and the basket. The reason the air in the balloon expands, is because as it is heated, the molecules of air move faster and spread out to fill the entire volume of the balloon.
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 is it possible that the volume of a helium tank is much less that 500 balloons it can fill?
The volume of a helium tank refers to the physical space it occupies and is not directly related to the number of balloons it can fill. When the helium is released from the tank and fills the balloons, it expands to occupy a much larger volume due to the low density of helium gas compared to its liquid form in the tank. This expansion allows the helium from a tank with a small volume to fill a larger number of balloons.
