Investigation of Relationship Between Pressure, Volume and Temperature of Gas

Suppose that the pressure of 1.00 L of gas is 380. mm Hg when the temperature is 200. K. At what temperature is the volume 2.00 L and the pressure 0.750 atm?

7) The gas accumulation in the balloon was measured and recorded at one minute intervals for a total of 10 minutes (qualitative observations were included)

B. How does this graph illustrate Boyle’s law? As more pressure is added the volume decreases and the graph shows this because it is decreasing as well. _________________________________

What about converting a given volume of gas to mass or a given mass to volume? Once again you have to get to that common ground first, which is the mole.

Temperature: Measure of the average speed of molecules rather than the total amount of heat energy in matter.

Think about the gas laws we are studying. Boyle’s law tells us that pressure and volume are inversely proportional. Charles’ law states that volume and temperature are directly proportional. We also know that pressure and temperature are directly proportional. Discuss at least one instance in your personal experience where you have seen one or more of these laws in action.

2. Read and record the temperature of the gas using the thermometer attached to the container.

7. Based on your data, what relationship exists between the pressure and the volume of a gas (assuming a constant temperature)?

3. The volume of a fixed mass of a liquid sample increases as the temperature rises from 20 to

In the fourth stage of this experiment, the density of a gas was determined. A 250ml flask was weighed with an empty rubber balloon and the mass was recorded.

To learn how concentration of reactants and products change with time and to distinguish (based on the trend) the order of the reaction.

To discover and observe what happens inside a ziplock bag when three substances are mixed together.

The purpose of this lab is to learn how to perform a lab, to learn how to measure mass and volume, to understand additive and non-additive properties, and to define density.

Robert Boyle, a philosopher and theologian, studied the properties of gases in the 17th century. He noticed that gases behave similarly to springs; when compressed or expanded, they tend to ‘spring’ back to their original volume. He published his findings in 1662 in a monograph entitled The Spring of the Air and Its Effects. You will make observations similar to those of Robert Boyle and learn about the relationship between the pressure and volume of an ideal gas.
