In this lab you will be investigating the effects of different environmental factors on the rate of transpiration in a plant. You will be using a. potometer. (a pipette attached to a rubber tube) to measure the rate of water loss in a plant.n this lab you will be investigating the effects of different environmental factors on the rate of transpiration in a plant.

The carâs radiator acts as a heat exchanger, transferring excess heat from the engineâs coolant fluid into the air. The radiator is composed of tubes that carry the coolant fluid, a protective cap thatâs actually a pressure valve and a tank on each side to catch the coolant fluid overflow.
A fuel cap for an automobile is made of metal or plastic. It secures the entry to the fuel tank. Mostly the caps have threads, which are fixed to the tank pipe with matching threads. A rubber gasket at the top gets compressed when the cap is fixed and stops the leakage of fuel.
