Transpiration from the leaves of trees is an example of:
Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. Transpiration also includes a process called guttation, which is the loss of water in liquid form from the uninjured leaf or stem of the plant, principally through water stomata.
Natural phenomenon like fog, mist or frost are caused due to:
Fog, mist or frost are due to condensation, depending upon the physical conditions of atmosphere.
Which statement regarding the effect of humidity on evaporation is correct?
Humidity refers to presence of vapour in air. So, if humidity increases then the rate of evaporation decreases as vapours in air are already present.
Vaporization starts at __________ point.
At Bubble point liquid starts evaporating which is the point at which vaporization starts.
Mixture containing ions ,atoms and electrons is known as
Mixture containing ions ,atoms and electrons is known as plasma. A Plasma is an ionized gas in which sufficent energy is provided to free electrons from atoms or molecules to allow both ions and electrons to coexist. Plasma is fourth state of matter.
