Sorry you've not had any responses about this. Are you sure you've posted in the right place? Here's a link to our subject forum which should help get you more responses if you post there.

I haven't done core science since last year
1) Direct proportion means both increasing at the same rate whereas the first result compares with the last result don't show direct increase. On a graph this would be y=x straight diagonal
2) Adv- more efficient so less energy wasted, which reduces running cost
2) disadv- Fridges release CFC's which are bad for the environment(google it but im pretty sure it destroys the ozone layer)
These aren't answers they're just guides
plus just find the markscheme if its too bad
