                In this experiment that I am carrying out, I am going to find out which material is best at insulating copper beakers. The materials that I am using are:



*Bubble wrap

*One with no insulator

Each material will be wrapped carefully around the beakers. Boiling water from a kettle will be poured into each beaker with a mass of 100ml; each beaker will have its own thermometer to measure the temperature. The temperature will be measured at eye level, where the reading will be taken. This experiment will last for 10 minutes, where at each 1 minute interval temperatures will be measured.

        My predictions on the experiment is that the cotton insulator will keep the boiling water warmest the longest period. The reason I think this is because cotton is the thickest material from the other material and has a lot of air particles trapped within the cotton (since air is a good insulator.) This causes less conduction. Although foil radiates the heat, its shiny surface absorbs extra heat from the surroundings (endothermic). However I still believe that cotton would be the best material for this experiment. I think the beaker that will have the lowest temperature will be the one with no insulator because it has no material to trap air and the dull surface, which will radiate most heat into the surroundings (exothermic).


        There is 3 ways which heat can be lost. The first method is conduction; this is where heat can be transferred from hotter to cooler regions and without movement from the substances.

If I was to do my experiment again, I would make the starting temperature at 100▫C by constructing a bigger beaker so there is larger capacity of boiling water, or the iron beaker could be a different material. The timing would be more accurate than the first test done by using a better stop clock that sounds at every minute. I will figure out the temperature by looking at eye level more cautiously to get an exact reading from the thermometer. The experiment will also be done for a longer period so there is a developed analysis of the Heat Loss experiment.

                If I had a longer period to do the test, I would do it several times then comparing the results with one another so the temperatures are accurate as they possibly can get. This will build a further better understanding of the investigation that I have planned to do.

    The limitation of ultrasound though is safety because there are ill effects such as low birth weight, speech and hearing problems. The argument though is that ultrasound is now a more 21st century technology and is becoming safer gradually. It is more accurate when it comes to assessing and monitoring pregnant women.

    The purpose of the control beaker is to compare the results of the experimental beaker to the control. The beaker is used to represent an animal; a small beaker represent small animal and a large represents a large animal. This was done because it is impractical to use real animals for the experiments; therefore beakers were used to represent them.

    The neighbouring particles cause their neighbours to vibrate too. Very soon all the particles vibrate vigorously and the whole solid feels hot. From this radiation is completely different from convection and conduction, as it does not involve particles at all.
