What does a graph representing Charles Law show?
Expert-verified answer Charle’s law states that the volume of a given mass of gas increases or decreases by of its volume at zero degree celsius for every one degree celsius rise or fall of temperature. Here, T is the temperature of the gas at kelvin. From above we see that .
What relationship does Charles Law show?
Charles’s law, a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant. This empirical relation was first suggested by the French physicist J. -A. -C.
What two factors does Charles Law explain a relationship between?
However, if the container volume is adjustable, the volume will increase, and the pressure will remain the same. Charles’ Law is the formal description of this relationship between temperature and volume at a fixed pressure.
Why is Charles Law graph straight?
At a fixed pressure, when the volume is varied, the volume-temperature relationship traces a straight line on the graph and on moving towards zero volume all lines intersect at a point on the temperature axis which is -273.15˚C.
What type of relationship is Charles law inverse or direct?
The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure (Charles’s law). The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle’s law).
What is the relationship between the volume and temperature of a gas according to Charles’s law?
Charles’s law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale when the pressure is held constant.
Why is Charles law graph explanation?
Mathematical explanation The graph is a straight line with a positive slope passing the origin. The equation of the line is V = kT, which is the equation of Charles’s law. The slope of the line is k. As temperature approaches zero kelvin, volume also approaches zero.
Why is Charles law graph straight?
Why is Charles law graph linear?
Graphical representation. The graphical representation of Charles’ law is demonstrated in the below graphs. The graph of volume vs temperature (in K) is a straight line passing through the origin. From the above graph, the volume increases linearly with an increase in the temperature.
Is Charles law a direct or indirect relationship?
Charles Law is a direct relationship between temperature and volume. When the temperature of the molecules increases the molecules move faster creating more pressure on the container of the gas increasing the volume, if the pressure remains constant and the number of the molecules remains constant.
What is the graph of Charles law?
What is the graph of Charles Law? The graph of Charles’s law is a volume-temperature graph. And it is as follows: The plot in the volume vs temperature (in K) graph is a straight line passing through the origin. The above graph is a volume vs temperature graph plotted as a constant pressure for a fixed amount of gas.
What is the relationship between volume and temperature in Charles’s law?
Volume is on the y – axis, and temperature is on x -axis. The graph is a straight line with a positive slope passing the origin. The equation of the line is V = kT, which is the equation of Charles’s law. The slope of the line is k. As temperature approaches zero kelvin, volume also approaches zero.
What is a modern statement of Charles law?
A modern statement of Charles’s law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be in direct proportion. What does Charles Law show a relationship between?
Why does Charles’ law hold for real gases?
Charles’ law holds good for real gases only at high temperatures and low pressures. The relationship between the volume and temperature is not linear in nature at high pressures. At high pressures, the repulsive forces among the molecules are significantly increased which causes the expansion of the volume.
