What does the slope of a pressure vs 1 volume graph represent?
P × V is a constant! Then a graph of V against 1/P, should be a straight line with a slope (or gradient) equal to the value of the constant. As gas volume (V) increases, the value of 1/P increases. As gas volume (V) decreases, the value of 1/P decreases.
What is 1 p in Boyle’s law?
According to Boyle’s Law, an inverse relationship exists between pressure and volume. The relationship for Boyle’s Law can be expressed as follows: P1V1 = P2V2, where P1 and V1 are the initial pressure and volume values, and P2 and V2 are the values of the pressure and volume of the gas after change.
What is the slope of pressure vs 1 volume?
Because the relationship between pressure and volume is an inverse relationship, the graph of pressure vs. 1/ volume should be direct; that is, the curve should be linear and pass through (or near) the origin. The slope of the line is equal to the proportionality constant k as established by Boyle’s law, PV = k. 1.
Will V vs P give a straight line?
The graph of V against 1p is a straight line through the origin. This means that the measured volume is inversely proportional to the pressure — Boyle’s Law.
Is P against V linear?
Since P and V are inversely proportional, a graph of 1/P vs. V is linear.
Why is Boyle’s graph curved?
The graph of Boyle’s law is called the PV curve. This graph of Boyle’s law is not straight but hyperbolic; this is because the statement says that at a constant temperature the pressure and the volume are inversely proportional. So when the pressure is increased the volume decreases and vice-versa.
What is the V vs 1 p graph?
V vs 1/P : Variation in volume (V) plotted against (1/P ) at a constant temperature, a straight line passing through the origin is obtained. V vs P: Variation in volume (V) plotted against pressure (P) at a constant temperature, a hyperbolic curve in the first quadrant is obtained.
Which is true of the graph of pressure and volume?
The graph of pressure volume vs volume at different temperatures. The graph above is a straight line parallel to the x -axis. This proves the product of pressure and volume at a constant temperature and amount of gas is constant. The lines in the graph are independent of volume (or pressure).
How does your graph of P versus 1 V illustrate Boyle’s Law?
The graph of V against 1/P is a straight line through the origin. This means that the measured volume is INVERSELY PROPORTIONAL to its pressure — BOYLE’S LAW. This says that when 1/P=0 , V= – 0.08 cm3.
Which is the graph between P & V at constant temperature?
Graph between P & V at constant temperature is a smooth curve known as “parabola”. Graph between 1/P & V at constant temperature is a straight line. It is quantitative relation between volume and absolute temperature of a gas at constant pressure.
