Answer:

The value of y is 2.

Step-by-step explanation:

1/3 ( y + 7 ) = 3 ( y - 1 )          Distribute

1/3y + 7/3   = 3y - 3              Subtract 1/3y on both sides

          7/3   = 2 2/3y - 3       Add 3 on both sides

          5 1/3 = 2 2/3 y           Divide 2 2/3 on both sides

               2  = y

The volume of a gas is 10.0 liters and its pressure is 1.5 atm. If the pressure is decreased to 0.75 atm,
JulsSmile [24]

Answer:

The new volume is 20litres

Step-by-step explanation:

This problem bothers on the expansion of gases

According to Boyle's law

The volume of a given mass of gas at constant temperature is inversely proportional to the pressure

P∝1/v

Pv= constant

Given data

P1= 1.5atm

v1 = 10 litter

P2=0.75atm

v2=?

Applying P1v1= P2v2

v2= P1v1/P2

v2= 1.5*10/0.75

v2= 15/0.75

v2= 20litres
