Question

describe an activity to show that hot air rises upwards .

Answer 1

HI HERE IS UR ANSWER

Back to warm air. Air molecules are independent, orbiting objects about the Earth in a vacuum that occasionally interact with other objects such that by increasing the velocities of the molecules, you are increasing the average velocity about the earth for them. When you do that, the individual orbits of the molecules increases, making the average molecular “weight” decrease while the masses stay the same.

As odd as it may sound, warm air rises because it is warmer.
