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.
In order to understand the function of a coolant reservoir, it is necessary to first gain an understanding of how the whole cooling system works. You must have noticed that your carâs hood becomes hot after it has been running for some time. In addition, the radiator, set beside the car engine, also heats up.
