It is difficult to burn a heap of green leaves but dry leaves catch fire easily.
Explain.

i dont really have explaining but see green leaf have some amount of water and chlorophyll so it doesn't get burnt and dry leaves lose water and have no amount of them so they get burnt

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
