Gas, liquid, and solid are known as the three states of matter, but each state may exist in one or more forms. A solid has a definite shape and volume. A liquid has a definite volume but the shape relates to its container. Gas fills the entire volume of a container. What is the relationship between volume and temperature at constant pressure for a given mass of a gas? Calculate the value of R in SI units? How Dalton’s law is useful in determining pressure of a gas collected over water?
Deviation of real gases is more at high pressure and low temperature, why? What is the significance of van der Waal’s constant a & b? How are they expressed? At higher temp isotherm moves away from both the axes because of increase in? The concept of distribution of velocities among the gas molecules was developed by? Under what conditions of temperature and pressure will a real gas behave most like an ideal gas? If all measurements are made at the same temperature what is the pressure in the combined arrangement after connection? Sudden expansion of gases is called joule Thomson effect?
The volume of one mole of an ideal gas at STP is 22414 cm3? The total pressure of the mixture of gases depends upon the total number of moles of the gases? The absolute zero is attainable temperature? Two grams H2 and 16grams oxygen contain equal number of molecules? Joule Thomson effect helps in liquefaction of gases? Liquefaction of gases involve increase in cohesive forces? Thirty two grams of sulphur and 23 grams of sodium contain Avogadro’s number of atoms?
