Table 3: Temperature vs. Volume of Gas Data

Temperature Conditions

Temperature (°C)

Volume (mL)

Room Temperature

Hot Water

Ice Water

I was doing this experiment and my pipette broke. What should the numbers look like for this? A general idea of how the volume changes would be great. Like about what the volume would be if its hot vs cold. These are the instructions:

Fill the syringe halfway with air, and seal the syringe by screwing the cap on. Record the volume (mL) of gas in the cylinder in Table 3.

Use the stopwatch and hold the top of the thermometer up in the air for thirty seconds. Record the temperature of the room in Table 3.

Fill one Styrofoam® cup with hot water from the sink. Place the thermometer in the cup.
LAB SAFETY: Avoid using extremely hot water. Handle hot water carefully. Be certain it is cool before handling it directly.

Submerge and hold the air-filled syringe in the hot water for thirty seconds. Use the stopwatch to monitor time.

Gently push the piston down until the plunger cannot move any farther. Observe the new volume inside of the syringe. Record this volume and the water temperature in Table 3.

Prepare a cup full of water mixed with crushed ice. Repeat Step 4 - 5 for the cold water bath. Record your the volume and temperature in Table 3.

Explanation / Answer

Temperature

conditions

When the syringe was exposed to heat, the gas in the syringe expanded, which caused the volume to increase.

When the syringe was exposed to cool temperatures, the gas in the syringe compressed, which caused the volume to decrease.
