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.
Without a radiator cap pressure tester, it can be quite difficult to diagnose. If your radiator is spilling fluid around the cap as soon as you stop the car when it is overheating, you found the problem. Unfortunately, this is not the usual symptom of a bad cap. If it was only that easy.
