8. in 1787 the french scientist jacques charles observed that when he plotted the graph of
volume of a fixed amount of air versus the temperature of the air, the points were linear.
suppose that at 27°c a certain amount of air occupies a volume of 500 cm'. when it is warmed
to 90°c it occupies 605 cm”.
a. write the linear equation expressing volume in terms of temperature.
b. predict the volume at 60°c.
c. if the volume is 700 cm? , what is the temperature?
