# What is the formula for P1?

Boyle’s Law (Volume and Pressure relationship) P1V1 = k = P2V2 or P1V1 = P2V2 1 Page 2 Where P1 and V1 are the initial (condition1) pressure and volume of the gas and P2 and V2 are the final (condition 2) pressure and volume of the gas.

## How is P2 calculated?

p₂ = p₁ * V₁ / V₂ or p₂ / p₁ = V₁ / V₂ . As we can see, the ratio of the final and initial pressure is the inverse of the ratio for volumes. This Boyle’s law calculator works in any direction you like.

## What formula is P1 T1 P2 T2?

Gay-Lussac’s Law or Third Gas Law states that for a constant volume, the pressure is directly proportional to absolute temperature: P alpha T; also stated as P/T = K, where K is a constant, and similarly, P1/T1 = P2/T2.

## What is P1 V1 T1 P2 V2 T2?

Combined gas law: P1V1/T1 = P2V2/T2 Use the gas laws for pressure, volume and temperature calculations. Avagadro’s Law and the Ideal Gas Law. Avagadro’s law – Equal volumes of gases at the same temperature and pressure contain equal numbers of molecules. Standard temperature and pressure, STP, is 273 K and 1 atmosphere …

## What is p2?

What Postinor-2 is used for. Postinor-2 is an emergency contraceptive only. Postinor-2 is not intended as a regular method of contraception. It is used to prevent pregnancy when taken within 72 hours of unprotected intercourse. It is estimated that Postinor-2 will prevent 85% of expected pregnancies.

## How do you calculate pressure in chemistry?

1. P=nRTV. Calculate volume:
2. V=nRTP. Calculate moles:
3. n=PVRT. Calculate temperature:
4. T=PVnR.

## What is Boyle’s law P1V1 P2V2?

Boyle’s law: For a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. so PV= constant. or P1V1=P2V2.

## What does V1 T1 V2 T2 mean?

The relationship between volume and temperature is: V1 / T1 = V2 / T2 where V1 and T1 are the initial volume and absolute temperature and V2 and T2 are the final volume and absolute temperature (the Kelvin temperature, not the Celsius temperature).

## What is the formula of volume 2?

V₂ = V₁ / T₁ * T₂ . If you prefer to set the final volume and want to estimate the resulting temperature, then the equation of Charles’ law changes to: T₂ = T₁ / V₁ * V₂ . In advanced mode, you can also define the pressure and see how many moles of atoms or molecules there are in a container.

## Who discovered the formula V1 T1 V2 T2?

In mathematical terms, the relationship between temperature and volume is expressed as V1/T1=V2/T2. Alright. One of the gas laws that you might come across is called Charles Law, and Charles law was formed by Jacque Charles in France in the 1800s.

## Which law is signified by the relation V1 T1 V2 T2?

Charles law states that the volume of an ideal gas is directly proportional to the absolute temperature at constant pressure.

## How is p2 used?

Take 1 tablet by mouth with or without food as soon as possible after unprotected sex. This medication works best when it is taken within 72 hours (3 days) after unprotected sex. If you vomit within 2 hours of taking this medication, contact your doctor to ask if you need to repeat the dose.

## When should one take p2?

The pills should be taken within 72 hours of unprotected sex. However, they can still be taken up to 5 days after unprotected sex. The emergency contraceptive pill is much more likely to work if you take it within 24 hours of having sex.

## Can p2 be taken twice?

A: You can take it more than once a month, but we do not recommend using it as a main form of birth control – not only because of the cost but because you will have irregular cycles.

## What is the formula used to calculate pressure?

Pressure is the force per unit perpendicular area over which the force is applied, p=F/A.

## What is the formula for total pressure?

Ptotal = P1 + P2 + P3 + ….. 1)Use PV = nRT to calculate the individual pressure of each gas in a mixture. 2)Use the mole fraction of each gas to calculate the percentage of pressure from the total pressure assignable to each individual gas.

## Why is P1 V1 P2 V2?

It can be expressed as \$ P_1V_1 = P_2V_2 \$ where P1 is first pressure, V1 is first volume, P2 is second pressure, and V2 is second volume. Option B: Charles law: Charles’ Law states that the volume of gas is directly proportional to the temperature provided the pressure is kept constant.

## What law is ptotal P1 P2 P3?

Dalton’s law states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases. Mathematically, the pressure of a mixture of non-reactive gases can be defined as the summation: Ptotal=P1+P2+P3….
