This question is using the heat capacity formula: Heat Energy (j) = mass (g) x specific heat capacity x temperature change (c)
The question is 'A 5 gram block of aluminium was heated from 30 celcius to 100 celcius. How much heat energy was needed.
(The heat needed to raise 1 gram of aluminium was 0.9j)
Hope this explains it alright.
Thank you
