https://www.exploratorium.edu/snacks/sizing-up-temperature Sizing Up Temperature Explore Charles’s Law—in a syringe. Discover the relationship between the temperature and volume of a given amount of gas.

Move the plunger on the syringe so that one third of the barrel is full of room-temperature air.

Submerge the syringe tip into the room-temperature water. Draw up the colored water until the end of the plunger is at the maximum-volume marking on the syringe.

On a piece of notepaper, record the volume of air trapped in the barrel by subtracting the volume of the water in the syringe from the maximum volume of the syringe. Then record the temperature of the water in degrees Celsius.

Quickly transfer the syringe into a beaker filled with water of a different temperature (either heated in a microwave or cooled with ice), making sure that the barrel is fully submerged. Hold the syringe upright so the water blocks the opening at the tip and the air is trapped inside.

Wait a few minutes for the air trapped in the barrel to come to the temperature of the water. You will know that the temperature has reached equilibrium when the water level in the syringe stops moving. This means the temperature of the gas and liquid inside the syringe is the same as the temperature of the water in the beaker. When stabilized, record the temperature of the water in the beaker and the corresponding volume of air. (Note: If the water level in the syringe ever gets so low that gas bubbles come out, you’ll have to start over with less air!)

Repeat the process of transferring the syringe into the other three beakers until you have volume and temperature data for at least five different temperatures. Reheat or re-cool any beaker-water samples that have become room temperature.

Plot the points for each volume (ml) and temperature (K) on a Cartesian graph. Do you notice a trend?

Boyle's Law

Put a strip thermometer in a bottle and pump up the pressure while watching the temperature rise.
