3. State Charles' Law. Give its mathematical representation
and graphical representation.
Answers
Answer:
Charles' Law is a special case of the ideal gas law. It states that the volume of a fixed mass of a gas is directly proportional to the temperature. This law applies to ideal gases held at a constant pressure, where only the volume and temperature are allowed to change.
Graph between V and T at constant pressure is called isobar or isoplestics and is always a straight line. A plot of V versus t(°C) at constant pressure is a straight line cutting the temperature axis at – 273.15°C. It is the lowest possible temperature.
At constant mass and pressure density of a gas is inversely proportional to it absolute temperature.
Use of hot air balloons in sports and meteorological observations is an application of Charle's law.
Answer:
According to this law at constant pressure the volume of an ideal gas is directly proportional to its absolute temperature.
V1/T1 = V2/T2 ( pressure = constant)
