Aim: To find out how temperature affects the viscosity of oil. Equipment: Oil, water bath, thermometer, beaker and funnel, measuring cylinder Plan: Oil will be poured through a funnel into a beaker. We will be timing how long it takes the oil to pour completely out of the measuring cylinder and through the funnel. The oil will firstly be placed in a hot water bath to heat it up to a desired temperature. A water bath will be used as using a Bunsen burner to heat it up would be unsafe and the oil would explode....
As we were using a certain type of oil, it might have been designed to work at that sort of temperature.

As we were using a certain type of oil, it might have been designed to work at that sort of temperature.
Evaluation: In my opinion, the results I obtained were fair. I believe this as the three readings for each temperature were very similar. My results definitely show a fall in viscosity as the temperature rises.
To make my results more accurate, I could have used a larger temperature range, for instance I could have started the temperature range a 1oc and finished at 81oc. Perhaps this is an experiment I could od in the future.
Before starting my coursework I have decided to chose a factor that will affect the resistance of a wire. I shall do this by going through all of the factors that affect the resistance of a wire and how I would measuring each factor to find out which...

HYPOTHESIS We can recognize four types of substances due to their structure: ionic, metallic, covalent, and molecular. If a given substance has a metallic luster, is malleable and ductile, is a good conductor of heat and electricity, and has high melting and boiling points, than it is supposed to...

Introduction To investigate how the length of a wire affects resistance in an electric circuit, different lengths of wire will be placed in an electrical circuit and the effects will be observed. An ammeter and voltmeter will be used to measure the current and voltage in...

Physics Investigation Of Resistance Aim: to investigate how the electrical resistance of a wire changes in relationship to it?é??s length. Prediction: I think that as the length of the wire increases so to will the resistance of it. I also believe that the rate at which the resistance...
