1 Specific heat capacity

2 Starter: what are these words 1. Nitccnooud 2. Ahte 3. Ciifcpeeetlsaattn 4. Darnoitai 5. Ecovnncoit 6. pumeetreart

3 Learning outcomes Recall key words Determine the safe procedure to carry out the practical Evaluate your results

4 Specific heat capacity E = mass x SHC x change in temperature Mass = 1kg SHC Al = 900J/kg 0 C SHC Cu = 385J/kg 0 C

5 Specific heat capacity practical Equipment

6 Method Set equipment up, making sure to connect the power to the immersion heater Set the power pack to 12v Record the start temperature Turn the power on for 5 minutes, then switch power off Record the highest temperature reached Share results

7 Results table

8 MaterialTemperature at start 0 C Temperature at end 0 C Temperature difference 0 C

9 Specific heat capacity E = mass x SHC x change in temperature Mass = 1kg SHC Al = 900J/kg 0 C SHC Cu = 385J/kg 0 C So how much energy was used to heat your block? Was it different to another groups? Evaluate your practical.

10 Homework: due 9 th September In your books or on paper or on the computer draw a poster that explains the following key ideas: heat, temperature, specific latent heat and specific heat capacity. You must include an image for each key idea You must in your own words explain what these words mean
