Question

the graph shows the volume of a sample of gas as a function of temperature. use the graph to determine the volume of the sample at a temperature of 225 k.

Explanation:

Step1: Locate 225 K on x - axis

Find the value 225 on the temperature (K) axis.

Step2: Read corresponding y - value

Draw a vertical line from 225 K on the x - axis to the line on the graph, then draw a horizontal line from the intersection point to the volume axis. Read the value.

Answer:

562.5 mL (estimated value by visual - inspection of the graph)
