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 fixed and the volume is constant. This law was formulated...
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: 1. P1is the initial pressure 2. T1is the initial temperature 3. P2is the final pressure 4....
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 kept away from fire an...
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 Gay-Lussac’s Law, P1T2 = P2T1 Therefore, T1 = (P1T2)/P2= (1*250)/(1.5) = 166.66 Kelvin.
Exercise 2
At a temperature of 300 K, the pressure of the gas in a deodorant can is 3 atm. Calculate the pressure of the gas when it is heated to 900 K. Initial pressure, P1= 3 atm Initial temperature, T1= 300K Final temperature, T2= 900 K Therefore, final pressure (P2) = (P1T2)/T1= (3 atm*900K)/300K = 9 atm.

Define chemistry, matter, composition and property a. Chemistry = 1) the study of matter and its properties, 2) the changes that matter undergoes, and 3) the energy associated w/the changes b. Matter = anything that has BOTH mass and volume c. Composition = the TYPES and AMOUNTS of simpler substances that make up matter d.

In ionic bonding, more than 1 electron can be donated or received to satisfy the octet rule. The charges on the anion and cation correspond to the number of electrons donated or received. In ionic bonds, the net charge of the compound must be zero.
Understand the octet rule and how to read and write Lewis dot diagrams. Utilise Lewis dot diagrams to predict the bonding of simple molecules. In 2.2 ‘Electronic Configuration’, we discussed how valence electrons are essential to determining the bonding of elements. Generally speaking, elements want to achieve 8 electrons in their outer ...
