Science coursework- Insulation Name: Anil Chand Form: 10WA Science teacher: Mr. Aslam Aim: To find out what type of insulation holds the most heat for a can containing heated water. PLAN What factors will you be changing? The types of insulation For what factor will you be recording readings? The temperature lost What equipment will you use to measure this factor? A thermometer What factors will you keep constant to make it a fair test? Explain how you will keep each of these factors constant. I will be keeping the starting temperature the same. I could maintain this by using a thermometer at the start of every experiment to keep the temperature the same. I will also use the same volume of water. This will be achieved by using a measuring cylinder to measure the amount of water. ...read more.


The ways heat is lost are conduction and convection. Heat is lost through the sides of the an, which is called conduction. Conduction is when particles have lots of thermal energy which turns into kinetic energy (this is also why I now predict that the hotter the water will be, the quicker the heat is lost). This then makes the particles vibrate a lot, which collides with other particles, moving the heat along. This is called conduction. Convection is when the particles have lots of heat to rise, and then they cool down and they sink. This is noticeable in colored liquid being heated. The 1st best insulator of heat will be the cotton wool with the lid, second will be the cotton wool on its own because it has no lid which means heat can be lost through convection waves through the lid, 3rd will be the ...read more.


Safety I will wear safety goggles because of the boiling water. I will also wear an overall, so I do not burn my body with the water. I will wear gloves so I don't burn my hands with the boiling water. Instructions for the experiment 1. Collect all of the equipment needed for the experiment 2. set up the apparatus 3. We will start on the no-insulation experiment 4. heat the water to 70 degrees Celsius 5. pour the water into the can and drop the thermometer in 6. remember the safety 7. take the readings of 1 minute intervals for 10 minutes 8. repeat the experiment 3 times 9. write down the results 10. Repeat the whole experiment for the bubble wrap, cotton wool, and cotton wool with lid. 11. clear up safely ...read more.

  1. An Investigation Into The Factors Affecting The Temperature Rise of Water Heated Electronically

    In the real experiment I will record every result to three significant figures and record the time every 30 seconds. As well as this I will record each piece of data reliably as I will be measuring the exact mass of water using electronic scales and make sure my circuit is working before I start the experiment.

  2. To find out which type of insulating is the most efficient at keeping in ...

    It is the emission of heat waves. Heat- Form of energy possessed by a substance by virtue of the vibrating movement (kinetic energy) of its molecules or atoms. Heat energy is transferred by conduction, convection and radiation. It always flows from a region of higher temperature (heat intensity)

  1. Investigation into the factors that determine the temperature rise of electrically heated water.

    If more that one is varied then decisive conclusions can never be drawn as the effects of a single variable is unknown. For example, if mass of water is varied then power, time of heating and resistance of the heater must remain constant.

  2. Find out what insulator is the best from cotton wool, bubble wrap and plastic ...

    The more surface area there is on the boiling tube the more of the hot water will be in contact with the air and so the quicker it will cool. Insulation such as cotton wool and bubble wrap traps air that is a bad conductor this means that heat is trapped and the test tube stays hot.
