General Application of Boyle's Law

In summary, the conversation involves a Year 10 student seeking help on a question related to Boyle's Law. The question involves a piston with a block of mass 120 grams placed on it trapping 200cm³ of air in a container. After the block is removed, the volume becomes 250cm³. The student is aware of the formula P1V1=P2V2, but is unsure of how to apply it. The formula states that if you have a quantity of gas with pressure P1 and volume V1, and you compress it or let it expand, the pressure and volume will become P2 and V2. The student is asked to determine the mass of the piston and how it relates to the pressure changes.

Hello,
I am Year 10 student and would like to get help on the question below based on Boyle's Law.

A piston with a block of mass 120 grams placed on it traps 200cm³ of air in a container. When the block is removed, the volume becomes 250cm³. Find the mass of the piston.

In the question above i only know that you have to use the formula P1V1=P2V2, but i don't know how to apply it. Please can anyone help?

The formula means that if you have a quantity of gas with pressure P1 and volume V1, and you compress it, or let it expand, and afterwards the pressure and volume are P2 and V2, then
P1V1 = P2V2

you know the volume before and after removing the block. What can you say about the pressure, and how is this related to the mass of the block and the piston.
 

Related to General Application of Boyle's Law

1. What is Boyle's Law?

Boyle's Law is a gas law that states the inverse relationship between the pressure and volume of a gas at a constant temperature.

2. What is the general formula for Boyle's Law?

The general formula for Boyle's Law is P1V1 = P2V2, where P1 and V1 represent the initial pressure and volume, and P2 and V2 represent the final pressure and volume.

3. How is Boyle's Law applied in real life?

Boyle's Law is applied in various industrial and scientific processes, such as in the compression of gases, scuba diving, and the functioning of respiratory systems in humans and animals.

4. What are the units of measurement for pressure and volume in Boyle's Law?

The units of measurement for pressure are typically expressed in pascals (Pa) or atmospheres (atm), while volume is expressed in liters (L) or cubic meters (m3).

5. How does temperature affect the application of Boyle's Law?

In Boyle's Law, temperature is assumed to remain constant. However, if temperature changes, the relationship between pressure and volume becomes more complex and may require the application of other gas laws, such as Charles' Law or Gay-Lussac's Law.
