Distillation is a technique used to separate pure liquids from a mixture of liquids by boiling the mixture to the respective boiling points of the components and selective condensation. The pure liquid separated out after the condensation of vapors is called distillate. The distillate collected is expected to be pure. The purity of the distillate can be measured by recording the boiling point of that liquid. For example, if we have water separated out it should boil at 100 otherwise it can be treated as impure.

Explanation:
It is given that two loads have 0.75 Ampere current each. And, they contain 2500 milli ampere per hour Ni-Cd battery.
As both the loads are connected in parallel. Hence, total current will be calculated as follows.
I =
= 0.75 A + 0.75 A
= 1.5 A
=
= 1500 mA
Relation between time and capacity of battery is as follows.
Capacity = Current × time (in hour)
therefore, time =
=
= 1.667 hr
Thus, we can conclude that the battery provide power to the load up to 1.667 hours.
