Assertion: Bacteria, fungi, moulds and algae are viable particulates .
Reason: Smoke particulates consists of solid or mixture of solid and liquid particles formed during combustion of organic matter.

Assertion (A) : Water cycle maintains total water reserves on earth. Reason (R) : Water cycle involves continuous cycling of water into solid, liquid and gaseous forms of water.

Assertion: The spaces left between soil particles are called pore spaces. Reason: Many organism like bacteria, fungi etc, exist in the soil.

Assertion : Solid - Liquid mixtures are separated by crystallization. Reason : On cooling a hot saturated solution, solide is crystallized out.

Assertion : An electrostatic precipitator (ESP) is a particulate collection device that removes dust and smoke particles from flowing air using the force of an induced electrostatic charge. Reason : An ESP is a highly efficient device as it removes 99 percent of particulate matter present in the exhaust from a thermal power plant.
