Question

According to charles law, the pressure P in pascals of a fixed volume of gas is linearly related to the temperature T in degrees celcius. In an experiment, it was found that when T =40, P=90 and when T=80, P=100.

a. What is the slope of the line containing these 2 points?
b. explain the meaning of slope in this context.

Answer 1

If my memory serves me well, according to charles law, use this formula: m=(P2−P1)/(T2−T1). This is A.
In this cotext, slope is the constant.
