Small cut made in gum tissue or nail quick, allow to bleed freely do not touch wound directly. Bleeding should stop within about 5 minutes.
The animation below gives and explanation of Charles' law: A sealed cylinder with no leaks contains a fixed mass. In order to keep the gas pressure constant the piston is allowed to move freely so that the internal pressure created by the gas particles can equal the constant external pressure.
If the internal pressure increases the piston will move up to allow the pressure to equalise. The above set up is used to investigate the relationship between temperature and volume for a gas.
Heat energy is applied to the cylinder and the temperature of the gas increases. The average velocity of the gas particles increases resulting in an increase in the rate of collisions and the average force per collision.
This produces an increase in pressure inside the cylinder, the cylinder pressure becomes greater than the external pressure and the piston moves up increasing the volume.
6) Calculate the moles of vapor from its pressure, volume, and temperature, and from this value and the mass of the vapor, calculate the molar mass, or molecular weight, of the vapor. 7) Be sure to return all equipment to its proper storage location. can be found by measuring the volume, temperature, and pressure of the trapped gas at a temperature near 0 C, where the water vapor content is less than one percent and can be neglected.

By plotting the recorded values of volume V against temperature T a straight line is produced. We can see from the values that the gas expands uniformly with temperature.
We can extrapolate the straight line and see the relationship between cooling the gas and the volume. Further extrapolation gives the temperature at which the volume of gas would become zero.
Converting the recorded temperatures into the Kelvin scale and plotting the volume V against the absolute temperature T gives a straight line which when extrapolated passes through the origin.
This shows the volume of the gas is directly proportional to the absolute temperature of the gas. Doubling the temperature will double the volume. What is the volume of gas?Lab Gas Properties Equipment: Computer station, Excel, investigate the relationships between pressure, temperature, volume, and velocity of the particles in an ideal gas.

Temperature and Pressure Measurements of an Ideal Gas That Is Heated in a Closed Container Introduction This report discusses an experiment to study the relationship of temperature and pressure of an ideal gas (air) that was heated in a closed container.
pressure, volume, temperature and number of moles of H2 gas. Calculation of the molar volume (volume of one mole) of H2 gas at STP conditions [temperature of 0° C ( K) and pressure of 1 atm ( torr)] will also be done].
The above data shows a positive and relatively linear association between pressure and temperature. It is important to notice that the pressure at 73 degrees Celcius is higher than the pressure . volume, pressure, and temperature of the gas we are able to calculate a value for R if the quantity of the gas is.
Atmospheric pressure in the laboratory is available from a barometer on the Your final report should include your reported value for R.
Report your value to the correct number of significant. • The atmospheric pressure (use the lab barometer), in mm Hg • The temperature of the water in the plastic tub (use the thermometer), in °C • The vapor pressure of water at the above temperature (obtain from Table on page 2), in mm Hg.
