Question

in this experiment a student found that when she increased thetemperature of a 550 mL sample of air from 22.3 C to 29.7 C , thepressure of the air went from 1009 to cm H2O up to 1033 cm H2O.since the air expands linearly with teperature P= mt+b Where m isthe slope of the line and b is the constant. What is the slope ofthe line? Find the value of b. Express the equation 9 in terms ofthe values of m and b. At what temperature t will P become Zero? .The temperature in part d is the absolute Zero of temperatue.Showthat on the kelvin scale you equation reduces to P= mT
