The volume of a gas

Advantages of modern periodic table

spayn [35]

Answer:

It organizes all of the elements and it allows you to easily find the groups of elements such as

Group 1 of the periodic table consists of hydrogen and the alkali metals

Group 2 consists of the alkaline metals (batteries!)

Groups 3–12 contain transition metals

Groups 13–16 each contain at least one metalloid

Group 17 contains halogens

Group 18 consists of noble gases which are stable.

It is easy to read and theres a song to help you memorize them online.

What are the gas laws? (Include Boyle's law, charles's law, gay lussac's law, an avogadro's law) Could someone please summarize

Rina8888 [55]

Answer:

Boyle's Law: When the pressure of a gas increases, the volume of the gas will decrease as long as the temperature and amount of gas are constant.

So basically pressure is inversely proportional to Volume, when one increases, the other decreases, vice versa.

Equation: $P_{1} V_{1} = P_{2} V_{2}$

Charles Law: When the temperature of a gas increases, the volume of a gas will also increase if the pressure and amount of gas are constant.

So basically Temperature and volume are directly proportional.

Equation: $\frac{V_{1}}{T_{1}} = \frac{V_{2} }{T_{2} }$

Gay Lussac's Law: When the temperature of a gas increases, the pressure of a gas also increases when volume and the amount of gas remain constant.

Basically, Temperature and Pressure are directly proportional.

Equation: $\frac{P_{1}}{T_{1}} = \frac{P_{2} }{T_{2} }$
