Introduction

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.

Conclusion

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.

    Conduction: Conduction is when energy is passed directly from one item to another. If you stirred a pan of soup on the stove with a metal spoon, the spoon will heat up. The heat is being conducted from the hot area of the soup to the colder area of the spoon.
