Question

DIRECTIONS: Solve the following problems by using G.R.E.S.A (Given, Required,Equation, Solution, and Answer).

Answer 1

Answer:

SEE BELOW

Explanation:

Given   500 cm^3 = V1    760 mm = P1     (760*2) = P2

Required   V2

P1V1 = P2V2

RE-ARRANGE  TO    P1V1/P2 = V2

(760)(500) /(760*2) = V2

V2 = 250 ML

Answer 2

According to Boyles law

$\\ \rm\Rrightarrow P\propto \dfrac{1}{v}$

• So if pressure is increased volume will be decreased and vice versa

Now pressure is doubled means multiplied by 2

The volume will be divided by two of get halved .

New volume

• 500/2
• 250cm³
