Hot Air Balloons

Hot Air balloons are safe.While moving because there is control.Similar to a stove,a hot ail balloon has a knob to control the heat.If the heat is nigh,the hot air increases in the balloon causing the balloon to go up,if the hot air decreases the balloon will go down.This happens because heat always rises.This is an example of convection.

Time for a Tan...

Radiation is the transfer of energy in electromagnetic waves,such as placing cold hands over a warm fire or laying out in the sun to get a tan. Convection is the transfer of heat through the movement of fluid. A pot sitting on a hot burner is an example of conduction. Using a heating blanket will make your body warms because it transfers heat energy.
