Post-Lab Questions

Use a pencil and graph paper to create a graph of temperature and volume data. Place temperature on the x-axis (in Kelvin) and volume (mL) on the y-axis. You can also use a graphing program to create your graph. Attach the graph to your Data Sheet by either taking a picture of your graph and pasting it below Table 1, or inserting a picture of your graph generating by a graphing program below Table 1.

What happened to the volume of gas when the syringe was exposed to various temperature conditions? Using the concepts explored in the Introduction, describe why this occurred, keeping in mind the definition of temperature.

Using a ruler, draw a straight line of best fit through your data points, extrapolating the line until it intersects the (negative) x-axis. Why can you assume a linear relationship (a straight-lined slope)?

At what temperature does your line intersect the x-axis? What volume corresponds to this temperature?

Answer 1

As the syringe was placed into the hot water, the molecules of the gas becameexcited and the air space between the molecules expanded, resulting in an increasedvolume. This is directly proportional to the increase in temperature.As the syringe was placed into the ice water, the molecules became lessactive, the air space lowered and the volume decreased.

Since Pressure is Constant, According to Charle's Law,

based on which we can assume a linear relationship between volume and temperature.

Line will Intersect the x-axis,
