Question

Which statement is true about the particles in liquid water at 100ºC and the particles in steam at 100ºC? (Select ALL that apply)
the particles will have the same kinetic energy
the space between the particles is different, with more space between particles in a gas
the particles will have different kinetic energy
the space between the particles is different, with less space between particles in a gas

I've been trying to figure this out for three hours, and I STILL don't know what it is.

Answer 1

the space between the particles is different, with more space between particles in a gas
the particles will have different kinetic energy

Answer 2

The average KE of a substance is a function ONLY of its temperature; therefore the state doesn't matter the KE of liquid water @ 100 and gaseous water @ 100 C is the same. And you know the molecules of H2O are farther apart in the gas than in the liquid. So pick out those two in the answers and get a good night's sleep.

Answer 3
