How do they change between each other? How do they get from phase to phase?
Does heat effect this? And can I change animals? I have too many legs.
But on the topic of your first question about heat..
Yes it does, and.... sure you can change animals. Why not?
Heat energy, or thermal energy, is transferred to other objects in 3 different ways. Convection, which is when the circular motion that happens with warm air or liquids, which has faster moving molecules, making it a bit less dense, rises in heat, while the cooler air of temperature drops. Conduction, which is when a hot substance touches a not-so-hot substance, warmer that up so t becomes hotter. Like hands hovering over a fire. And last but not least, Radiation. That happens when the heat waves from a hot object travels to the less hot object. I like to think of the Sun's heat rays travelling to the Earth.
Wait, but what about the pepperoni pizza?
Now you know the states of matter, how they chnage between each other, and how thermal energy works!
Shoot! I'll eat this any way though. Wait, who's this guy? Aw, shoot!
Unfortunately, pepperoni pizza is NOT vegan. Sorry everybody.
