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?

Heart also can melt

well there is a temperature point for an objects state to turn into ether gas, liquid, or solid form.
With enough heat, solids objects can be melted.
just that you may not see the change in state from an eye point.

Paper cannot melt!
tree cannot melt!!!

interesting question...

i have a question too...so in order to contain something that melts at very high temperature, the container needs to have higher melting point...how they make this container and how they melt this container again, as they would need another higher melting point container...its like endless cycle...

water cannot melt too

universal cannot melt.

not everything can be melt.

Power create heat, heat melt object & release energy (power).
energy cooldown become object form.

let's say...u got powerful heat that can melt everything....but how long can the power support.

after melt everything, the power gone. & it cool dowm. Gas=liqui= object form.

it recycle.

this

zzz....


everything can melt.... but whether they melt or vaporize.... it depends on pressure.... i forgot though.. but thr is this graph i saw.....

at normal atmospheric pressure..... some items instantly vaporize.... example.... dry ice.. haha...... frm solid>gas...

take that dry ice... put in a chamber with high enough pressure... it will be. solid>liquid>gas....


haha...

i forgot the terms... lolx.. ought to do revision me.

but nevertheless.. a good question. ^^

this is right.. i dont think anyone draw a graph on meat mayb post starter could try.

lolx... i wan the graph for vegies!!!! imagine.. liquid vegy.....yer. yuck

anyway.

@ts..

question answered?? or...?

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.

i forgot bout that. thx.

i bliv everything can melt . based on what temperature of heat we are giving it . if it does not we can use high pressure + high heat to melt it as well ... =D

theyll turn to dust. but you can melt them if you put in blender
