hich statement best explains why a hot-air balloon rises when the air in the balloon is heated?
According to Charles’s law, the temperature if a gas is directly related to its volume. Thus the volume of the balloon increases, decreasing the density.
Hot air rises inside the balloon, which 1ifts the balloon.
The temperature of a gas is directly related to its pressure. The pressure therefore increases, which lifts the balloon.
Some of the gas escapes from the bottom of the balloon, thus decreasing the mass of gas: in the balloon This decreases the density of the gas in the balloon, which lifts the balloon.
Temperature is related ten the velocity of the gas molecules. Thus the molecules are moving faster, hitting the balloon more, and lifting the balloon.
