how is temperature and volume related?

Temperature is an indicator of how active the particles of a substance are... the hotter a substance is the more excited the molecules.

As substances heat up, they expand because of the molecules moving around so much taking up more space.

So as temperture increases so does volume.

Take a cup of hot coffee or tea. Watch as it gets cold and you will see the level on the cup drop. The volume has reduced because cooling allowed the molecules to move closer together.

g-day!

What is Volume?

Volume is the amount of space that something takes up. Solids have a fixed volume and shape. Liquids have a fixed volume but take the shape of their container. Gases take the volume and shape of their container.

What is Temperature?

Temperature is most commonly thought of as how hot or cold something is. More precisely, temperature is related to the measure of the average kinetic energy of the particles of a sample of matter. This matter can be in any state. Matter is made up of atoms and molecules, and these particles are constantly moving. (Only at 0 Kelvin does all motion stop. This is known as absolute zero, and represents the lowest temperature possible.)

In simpler terms, if volume is constant, an increase in temperature results in a proportional increase in pressure. If pressure is constant, an increase in temperature results in a proportional increase in volume. Inversely, if volume is decreased and pressure remains constant, temperature must decrease. Basically, pressure and volume are directly proportional to temperature and inversely proportional to each other.

I Would have thought they are not related expect both can be measured and contained.

Hmm, i guess the effect of tempreture would affect the volume? Like when you freeze water it has less volume because the particles can't move, but unfrozen they particles (is particles the right word..) can move and have more freedom!

You can create tempreture and volume and measure it, but they are both measured in different systems...I don't know, I was only good at biology sorry!

In general, volume increases with increasing temperature. There are some interesting exceptions, of which water is by far the most important.

PV=nRT As the temperature increases, so does the volume (unless the volume is fixed, in which case the pressure must increase.)

As temperature increases, volume increases.

In gases, the volume is directly proportional to the temperature

Gay-Lusac's Law -Volume of a gas is directionally proportional to temp--.PV=nRT is a combination of Boyle's,Charle's and Gay Lusac's laws.

how ARE the temp. pressure and volumn related?

Fixed V, p=kt

Fixed p , t=k/V

fixed t, p=k/v

They are directly releated one goes up the other goes up. I think I learned it this way t1v2=t2v1
