An experiment using DrDAQ to measure the affect that temperature has on pressure other and the sides of the container and hence the pressure is increased.

## What’s the relationship between pressure and temperature of gas?

Does an increase of pressure also increases the temperature of the gas? For an ideal gas being compressed adiabatically, the answer is an emphatic yes. For anything else, the answer is sometimes yes, sometimes no. The answer depends on how much heat is being transferred into or out of the gas and on the nature of the gas. If the gas is right at the triple point ideal gases don't have a triple pointall that compressing the gas adiabatically is going to do is cause some of the gas to turn into liquid or solid. Excluding water and other special materials, why does a increase of pressure over a solid rises is melting point? What your teacher told you is nonsense. Increased pressure does not decrease the molecule's motion. What increasing the pressure does do is to decrease the intermolecular distance. Also same as before, initial and final volumes and temperatures under constant pressure can be calculated. The Pressure Temperature Law This law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. P Same as before, a constant can be put in: The Volume Amount Law Amedeo Avogadro Gives the relationship between volume and amount when pressure and temperature are held constant.

### Temperature and Pressure Effects

Remember amount is measured in moles. Also, since volume is one of the variables, that means the container holding the gas is flexible in some way and can expand or contract. If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases. V As before, a constant can be put in: The Combined Gas Law Now we can combine everything we have into one proportion: The volume of a given amount of gas is proportional to the ratio of its Kelvin temperature and its pressure.

Same as before, a constant can be put in: The Ideal Gas Law The previous laws all assume that the gas being measured is an ideal gas, a gas that obeys them all exactly. As temperature rises, the kinetic energy of the molecules within the solid begin to vibrate, which decreases the attraction of these molecules.

## Temperature and gas calculations

There is a temperature threshold, referred to as the melting point, at which the vibration becomes sufficient enough to cause the solid to change to liquid. The melting point, in turn, also identifies the temperature at which the liquid will change back to the solid, so it is also the freezing point.

The Boiling or Condensation Point In a liquid, molecules are not as tightly compressed as in a solid, and they can move around. This gives liquid the important property of being able to take the shape of the container in which it is held. As the temperature -- and thus the kinetic energy -- of a liquid increases, the molecules begin to vibrate more rapidly.
