1. Boyle's law
2. Charles's law
3. Avogadro's law

Charles's law states that the volume of a gas is directly proportional to the temperature of the gas, while pressure and number Of moles are kept constant (V/T = constant). All temperatures must be in kelvins when used in gas law calculations.

Boyle's law states that the volume of the gas varies inversely to the pressure on the gas, while temperature and number of moles are kept constant (PV = constant).

Avogadro's law states that the volume of a gas is directly proportional to the number of moles of the gas, while pressure and temperature are kept constant (V/n constant).

Explanation:

Charles's law says that at constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases. This is because "temperature" means movement of the particles. So, the greater the movement of the particles (temperature), the greater the volume of the gas. Then, Charles's law indicates that the volume is directly proportional to the temperature of the gas.

So, Charles's law states that the volume of a gas is directly proportional to the temperature of the gas, while pressure and number Of moles are kept constant (V/T = constant). All temperatures must be in kelvins when used in gas law calculations.

As the volume increases, the gas particles (atoms or molecules) take longer to reach the walls of the container and therefore collide with them fewer times per unit of time. This means that the pressure will be lower because it represents the frequency of collisions of the gas against the walls. In this way pressure and volume are related, determining Boyle's law which says:

"The volume occupied by a given gaseous mass at constant temperature is inversely proportional to pressure"

So, Boyle's law states that the volume of the gas varies inversely to the pressure on the gas, while temperature and number of moles are kept constant (PV = constant).

Avogadro's Law is a gas law that relates the volume and quantity of gas at constant pressure and temperatures. This law states that the volume of a gas held at constant temperature and pressure is directly proportional to the number of moles of the gas: if the amount of gas increases, the volume will increase, and if the amount of gas decreases, the volume decreases.

Then, Avogadro's law states that the volume of a gas is directly proportional to the number of moles of the gas, while pressure and temperature are kept constant (V/n constant).

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
