are volume and temperature direct or indirect?

Answer 1

They are direct. In Charles's Law, it's V1/T1 = V2/T2
Since they are proportional, they must have a direct relationship.

Answer 2

Very much direct. the definition of volume is the space occupied by an object. While the temperature boils down to the kinetic energy of a specific set of materials ( for example a block of Aluminium [Al] is 25C then it is assumes that all the Al atoms have the kinetic energy of, etc. etc. etc).
What does kinetic energy have to do with this??? Well imagine you have a chamber with 10 balls (these balls easily translate to atoms in the gas and liquid phase) moving around the chance that they will bounce off each other is related to the size of the room (IE a 1m3 room is smaller than a 100m3 room thus there is a higher chance of of the balls hitting each other in the smaller room. So if these ball had a higher temperature thus more energy and thus more kinetic energy the higher speed they cover. The hihger speed they cover the longer path lengths they travel and with the thigher path lengths the balls have a higher chance of striking other and thus will bounce off and fly further aparrt. Think of pool. A good pool break usually is when the cue ball hits the racked balls hard as possible and results in a large area to be covered by the other balls. If you hit the racked balls softly theire is hardly a break at all. Well I hope this helps and that I haven't confused you.

here is a real cool video of a prof cooling a ballon with Liquid nitrogen and you can see the volume (size of teh balloon) shrik and a good animation of what is happening insode the ballon on google.

The ideal gas law PV=nRT also shows a big relationship between Voulume V & Temperature T. I hoped I helped

Answer 3

Direct proportion. V1/T1=V2/T2

Answer 4

direct

Answer 5

yes, direct

Answer 6

direct

Since pV= nRT

V=nRT/p
