Answer 1

An increase in the number or size of dust particles in air leads to warming because:

When the number or size of dust particles increases in the air it interacts with the solar beams making the dust to absorb heat and in turn heat up the air around it. The dust will absorb solar radiation before it reaches the ground, which leads to warming of the surrounding air. This is the reason why when there is increase in dust or size of dust in the air the air gets warm.
