Question

what is the key difference between a liquid and a gas?
i can't decide between these two i have narrowed it down to:
a. motion of particles 
b. average kinetic energy

anonymous · Answer

i think its a because the motion of particles in water are flowing together and in a gas they flow freely

anonymous · Answer

but wouldn't that also make their kinetic energy higher? that's what confuses me

anonymous · Answer

lol yea but thats not the main difference the particle movement is a bigger difference try it and let me know if thats right im pretty sure it is

anonymous · Answer

ok, can you answer 3 more?

anonymous · Answer

yea sure

d. cannot be measured

anonymous · Answer

increases because there is less volume of water to be heated

anonymous · Answer

thanks! i already found the other answers!

For 1 the key difference is actually inter-molecular attraction 
And for 2 it actually decreases
