Question

what happens when the molecules are heated?
and however, a high or prolonged temperature can be deadly?
plz explain 2 meeH why???

Answer 1

they speed up!

Answer 2

they gain kinetic energy of course and they move faster and till a point when a change of state takes place. a high or prolonged temperature can be deadly because cells will die if they are exposed to high temperatures and for a long time

hope this helps!(:

Answer 3

molecules' electrons run faster and farther, and making molecules themselves apart aways. thus H20 may changes from liquid to gas in status if we heat them up.

I believe they will be excited if high temperature apply to them instead of dead...if you talk about molecules.

Hence, too much of exicitement will lead to dead....don't take drug...

Answer 4

they speed up and friction causes the eletrons to fall off which dicentagrates the molicuel i thought u said cell

Answer 5

The electrons of the individual atoms increase in speed.
Deadly for what???
