Charles’ Law is an experimental gas law that describes how gases tend to expand when heated. The law states that if a quantity of gas is held at a constant pressure, there is a direct relationship between its volume and the temperature, as measured in degrees Kelvin. Think of it this way.

Charles’s Law says that the volume of a gas is directly related to the temperature of that gas, similarly when a gas is heated, like a burner in a hot air balloon, the gas expands. So when the air inside the balloon expands, it becomes less dense and provides the lift for the hot air balloon.

By heating the air inside the balloon with the burner, it becomes lighter than the cooler air on the outside. This causes the balloon to float upwards, as if it were in water.

Boyle’s law

Explanation: Boyle’s law says that absolute pressure exerted by a specific mass of an ideal gas is inversely proportional to the volume it occupies. But when you blow up a balloon you do not have one specific mass of gas, because with every blow into the balloon you are increasing the mass of gas inside the balloon.

According to Boyle’s law volume of a gas is inversely proportional to thd pressure. But inflating ballon violates Boyle’s law because there is increase in volume with increasing pressure.

Boyle’s law is applicable to an isothermal process where temperature remains constant.

Answer. Answer: An ideal gas undergoes an adiabatic process obeying the relation PV^4/3 = constant.

Solids and liquids have intermolecular attraction between them, which provide their characteristic shape and properties, therefore the ideal gas laws do not apply solids and liquids.

As a gas (like air) expands, the value of V increases and this has the effect of increasing T (The temperature). As the energy needed to increase it’s temperature must be supplied from somewhere, the gas takes the energy from the surrounding system giving the effect of cooling.

Boyle’s Law holds true only if the number of molecules (n) and the temperature (T) are both constant. Boyle’s Law is used to predict the result of introducing a change in volume and pressure only, and only to the initial state of a fixed quantity of gas.

Boyle’s Law – states that the volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant.

Three Ways to Increase the Pressure of a Gas

1. Increase the amount of gas. This is represented by the “n” in the equation.
2. Increase the temperature of the gas. This is represented by “T” in the equation.
3. Decrease the volume of the gas. This is the “V” in the equation.
