Hey! Please could you help me with copper? I would like to check if my energy value is correct, then what steps you need to do after that. Thank you so much :smile:

Hey! Sure thing! Specific heat capacity of air= 1.012 jcm-1c-1

Steps to take:

1) Find Q from Q=mcΔT

2) Find moles of CH4 required to fill the room, use the knowledge that CH4 releases 891kJ per mole

3) Use n=v/24000 to find volume of gas

Answer should be 5 digits long! :wink: Good luck! You're almost there!
