15. (bonus)For an enclosed gas, if the pressure is constant what shape would you expect for a graph of the volume vs. temperature? (1 pt)

1 point
a straight line with a negative slope
a straight line with a positive slope
a straight line with no slope (horizontal)
a power curve with a power of -1
The correct answer is a straight line with no slope (horizontal). When the pressure of a gas is constant, the graph of volume versus temperature will be a straight line parallel to the x-axis (horizontal). This is because the volume of an enclosed gas is directly proportional to its temperature when pressure is constant, according to Charles's Law.
