Question

8 gram of helium gas what is the slope of the straight line in PV vs T graph

Answer 1

The steepness of a line is essentially the slope. When we see a line oriented from bottom left to upper right, it has a positive slope. A negative slope would be depicted by a line going from the upper left to bottom right.

Slope values increase the higher the number is: For instance, a line with a slope of 2 is steeper than a line with a slope of 12.
