Question

Volume of syringes reading read as 4cc when the weight (pressure) was 600g. Determine the pressure used (weight) when the volume is 2.5 cc?

Answer 1

`960\text{ g}`

Step-by-step explanation:

Here, we want to calculate the pressure used at the new volume

It is expected that at a higher pressure, the volume will decrease

Thus, the weight and the pressure are inversely proportional

Mathematically:

`P_1V_1\text{ = P}_2V_2`

The above is according to Boyle's law which states that volume and pressure are inversely proportional

where:

V1 is the initial volume which is 4 cc

P1 is the initial weight which is 600 g

V2 is the final volume which is 2.5 cc

P2 is the final pressure which is unknown

Substituting the values:

`P_2\text{ = }(600*4)/(2.5)\text{ = 960 g}`
