You could probably tell me what each of the words in the title to this post mean individually, but what does “specific heat capacity” mean when we put them all together?  Here’s a presentation we will use to find out a bit more about it.  Thanks to Mr Hobbins for producing it.   Specific-Heat-Capacity

Here is the handout with tons of practice questions: Specific-heat-Capacity-questions

We’ll come to an understanding of how heat (a form of energy) is different from temperature

And we’ll do a lab where we compare different types of fuel to find out which is most efficient.  Comparison of fuels lab

We’ll be looking at heat energy a little more closely and understanding it’s relationship to temperature.  This will lead us on to something called specific heat capacity.  What on earth is that?  Check out this presentation by Mr Hobbins: Specific Heat Capacity

Here is the worksheet we’ll go over in class: Specific heat Capacity questions

We’ll also be doing a lab where we compare different fuels to see which is more efficient.  Different groups will test different fuels, and then pool the data into the following spreadsheet. Comparison of fuels table and graph template

For homework you will be required to print out a copy of the table and graph, and then write up your conclusion.  You should also highlight sources of error in the experiment and suggest sensible improvements or alternatives.  This will be due on Friday 15th January.
