What is the effect of pressure in air movement ?
Air moves from the region of low pressure to high pressure
Air moves from the region of high pressure to low pressure
Air does not depend upon the pressure
Air does not move at all

What happen when water vapour changes back to liquid in the form of raindrops ?
Heat is absorbed
Heat is released
Heat is first absorbed and then released
there is no exchange of heat.
What is the function of a lightning conductor installed in a building ?
does not allow the lightning to fall on the building
repels the lightning
