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.

Airflow through the grille when the vehicle is at speed, or drawn though by the fan when the vehicle is idling or at low speed, flows through the radiator.
