The volume of a sample of a gas at a given pressure varies directly with
temperature. The table shows the volume
V of a sample of gas at different temperatures.
Part A: Explain why a direct
variation model can be used for the data.
Part B: What is the constant of variation,
to the nearest thousandth?
Part C: Write an equation of direct variation for these
data.
Part D: At what temperature does the sample of gas have a volume of 4.88 L?
Round to the nearest whole number.
Part E: What would be the volume of the sample if
the temperature is 150 K?
