Answer 1

Thanks everyone for your responses – I was confused mainly because in chemical reactions with flammable reactants (eg oxidation of ethanol), heating with fire is avoided but heating with other sources is fine, which I see is because of how hot fire is compared to most other sources of heat used in the lab.
