Boyle's law

Question 1

what is Boyle’s law

Answer 1

The pressure of an enclosed gas is inversely proportional to the volume it occupies at constant temperature.

higher pressure = lower volume

lower pressure = higher volume

Question 2

what happens when you compress gas

Answer 2

As the volume decreases as you compress a gas then the pressure will increase. This happens because now that the particles are closer togethers so they have more collisions and as the number of collisions increases so does the pressure.

Question 3

what does it mean by ‘enclosed gas’

Answer 3

the amount of gas or the number of moles remains constant. Let’s look at some concepts that you should have dealt with in Grade 10.
