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.
I had the same problem. My radiator cap was not keeping any pressure. When I would stop the engine hot, it would spill one or two cup of coolant throught the overflow tank and I would hear the coolant boiling in the engine.lose. My car has 110,000 mi.and I have replaced the radiator cap and had the system flushed and filled, also replaced thermostat, and overflow resovoir tank--and it still pumps coolant out the overflow and then starts to run hot.
