how does the graph of volume x pressure against volume look like? and why ?

Answers

Answered by wanderess099

If we take PV at y axis and V at x axis, then the graph is a straight line parallel to the x axis.

This is beacuse PV for a gas is constant at a particular temperature.

mahoolika4: thank you so much but could plz explain why PV for a gas is constant at a particular temperature?

wanderess099: Mention not. (: And pressure×volume for a gas is constant. We have various gas laws that probe the fact. And according to the ideal gas equatiob, PV =nRT. Here, R is called the real gas constant whose value is always same and n is the number of moles of the gas present. T is the temperature. So, if we keep T as constant, ie, temperature remains the same, then pressure×volume or PV will always be constant for that gas.
