What is the final volume of a gas with an initial volume of 75 ml if the pressure decreases from 300 kpa to 200kpa? a. 100 ml b. 50ml c. 75.5ml d. 112.5 ml

The final volume of the gas is 112.5 mL.              

Explanation:

It is given that,

Initial volume of the gas,

Initial pressure,

Final pressure,

We need to find the final volume of the gas. It can be calculated using the Boyle's law as :

p v = constant

or

, V₂ is the final volume of the gas

So, the final volume of the gas is 112.5 mL. Hence, this is the required solution.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
