Question

in this experiment a student found that when she increased the temperature of a 550 mL sample of air from 22.3 C to 29.7 C , the pressure 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 is the slope of the line and b is the constant. What is the slope of the line? Find the value of b. Express the equation 9 in terms of the values of m and b. At what temperature t will P become Zero? . The temperature in part d is the absolute Zero of temperatue.Show that on the kelvin scale you equation reduces to P= mT

Explanation / Answer

(a) m=3.2 cm h20/c*

(b) b=1.01
(c) P=3.2t+1.01
(d) t= -.34
