A: Hot air balloon rises up by displacing the denser air of the atmosphere.
R: The given mass of a gas becomes less denser.
R: The given mass of a gas becomes less denser.
View answer and explanation
Correct option: A
If both A and R are correct and R is the correct explanation of A
Option A is correct because the hot air balloon rises due to the heated air inside being less dense than the surrounding cooler air, as described by the relationship between density and temperature.
