____ + water to food + _____

The ratio of speed of sound in monomatomic gas to that in water vapours at any temperature is. (when molecular weight of gas is 40 gm//mol and for water vapours is 18 gm//mol )

Rainwater is formed by _____ of water vapour.

90 g of water spilled out from a vessel in the room on the floor. Assuming that water vapour behaving as an ideal gas, calculate the internal energy change when the spilled water undergoes complete evaporation at 100^(@)C . (Given the molar enthalpy of vaporisation of water at 1 bar and 373 K = 41 kJ mol^(-1) ).

A piece of silica gel is placed in the water vapours. Will the gel adsorb or absorb water vapours?

Assertion : In a terrestrial ecosystem, detritus food chain is the major conduit for energy flow. Reason : Solar energy is the direct source for energy supply in a detritus food chain.
