    Exercise 1 The pressure of a gas in a cylinder when it is heated to a temperature of 250K is 1.5 atm. What was the initial temperature of the gas if its initial pressure was 1 atm? Given, Initial pressure, P1 = 1 atm Final pressure, P2 = 1.5 atm Final temperature, T2 = 250 K As per…

    When a pressurized aerosol can (such as a deodorant can or a spray-paint can) is heated, the resulting increase in the pressure exerted by the gases on the container (owing to Gay-Lussac’s law) can result in an explosion. This is the reason why many pressurized containers have warning labels stating that the container must be…

    Gay-Lussac’s law implies that the ratio of the initial pressure and temperature is equal to the ratio of the final pressure and temperature for a gas of a fixed mass kept at a constant volume. This formula can be expressed as follows: (P1/T1) = (P2/T2) Where: P1 is the initial pressure T1 is the initial temperature P2 is…

    Gay-Lussac’s law is a gas law which states that the pressure exerted by a gas (of a given mass and kept at a constant volume) varies directly with the absolute temperature of the gas. In other words, the pressure exerted by a gas is proportional to the temperature of the gas when the mass is…

    Propane tanks are extensively used in the kitchen. It’s not enjoyable, however, to discover you’ve run out of gas halfway through a meal. On a hot day, gauges are used to measure the pressure inside gas tanks that read greater than on a cool day. When deciding whether or not to replace the tank before…

    Infinite dilution is a state of dilution in which the concentration does not change when more solvent is added. In chemistry, the concept of infinite dilution is used to investigate how compounds dissolve in different solvents.

    The Kohlrausch law can be used to calculate the limiting molar conductivities of any electrolyte. At larger concentrations, weak electrolytes have lower molar conductivities and a lower degree of dissociation.

    According to Kohlrausch’s law of independent ion movement, the limiting molar conductivity of an electrolyte can be described as the sum individual contributions of its cations and anions. Since fewer ions are present for conduction, a solution’s conductivity decreases with dilution.

    It’s used to determine an electrolyte’s dissociation constant. It’s used to find out what a weak electrolyte’s limiting molar conductivity is. This law can also be used to determine the degrees of dissociation of weak electrolytes.
