## Combined Gas Law Formula

The combined gas law states that the temperature is proportional to the product of pressure and volume. Boyle's law, Charles law, and Gay-law Lussac's are integrated in combined gas law. The relationship between temperature, pressure, and volume is described by this law. The system remains constant in this situation.

The formula for the combined gas law is as follows: PV/T = k

• Here, k is Constant
• P is pressure
• V is Volume
• T is Temperature

In order to compute the changes in temperature, pressure or volume a sample gas may suffer in certain conditions, the combined gas law can be written as:

(P1*V1)/ T1 =(P2 * V2)/(T2)

• Where, The initial pressure be P1
• The Final pressure be P2
• The initial temperature be T1
• The final temperature be T2
• The initial volume be V1
• The Final volume be V2

The temperature is by default expressed in Kelvin but can also be specified in Celsius or in Fahrenheit, as the calculator applies the following rules to convert it to Kelvin:

• °C to K = t°C + 273.15
• °F to K = (t°F + 459.67)*5/9

### Combined Gas Law Examples

Question 1: If the initial and final volume is 98 m3 and 50m3 , final pressure is 73pa with the initial and final temperature is 55k and 65k then What will be the initial pressure?

Solution:

Consider the problem, we have

Let the Final pressure be P2 = 73 Pa

Let the initial temperature be T1 = 55 K

Let the final temperature be T2 = 65 K

Let the initial volume be V1= 98 m3

Let the Final volume be V2 = 50 m3

The formula for finding the initial Pressure,(P1) V1)/ T1) =(P2 * V2 * /(T2)

P1 = 31.5149136577708 Pa

Therefore,The initial pressure of the Combined Gas Law: (P1) = 31.5149136577708 Pa

### FAQs on Combined Gas Law Calculator

1. State the combined gas law?

According to the combined gas law,The ratio between the product of pressure and volume and the temperature of a gas-based system remains constant.

2. Is the combined gas law inverse or direct?

When Boyle's law, Charles' law, and Gay-law Lussac's are combined, we get the combined gas law, which states that pressure is inversely proportional to volume, or that a larger volume equals a lower pressure. Temperature and pressure are directly related, therefore a higher temperature equals a higher pressure.

3. What is the purpose of this combined gas law calculator?

By combining the Charles and Henry Gas Laws, this Combined Gas Law Calculator can help you estimate the pressure, temperature, or volume of a gas.

4. What is the formula for calculating the combined gas law?

The Formula for calculate the Combined Gas Law is k=PV/T. So long as the number of moles in a gas remains constant, the constant k is a real constant. When the amount of gas changes, k changes as well.
