I know we probably learned this in physics but i've forgotten about it. Can everything melt if certain temperature are met? I know rock can melt at over thousand degrees, but what about other things like meat/paper etc? Because normally they'd burn off before they get the chance to melt into liquid form. Or they melt into liquid form after burning into ash?
You have to remember that meat and paper are compound substance. Sometimes, before the energy can change the physical structure, it is used to change the chemical structure first. That's why it got burnt rather melting first. The energy needed to change the chemical structure is lower than the energy needed to change the physical structure.
