An ideal gas is confined within a closed cylinder at a pressure of 2.026 × 105 pa by a piston. the piston moves until the volume of the gas is reduced to one-ninth of the initial volume. what is the final pressure of the gas when its temperature returns to its initial value?

The final pressure of the gas when its temperature returns to its initial value Pa.

Step-by-step explanation:

Given : An ideal gas is confined within a closed cylinder at a pressure of Pa by a piston. The piston moves until the volume of the gas is reduced to one-ninth of the initial volume.

To find : What is the final pressure of the gas when its temperature returns to its initial value?

Solution :

Since the temperature is constant .

The relation between P and V is given by,

....(1)

The piston moves until the volume of the gas is reduced to one-ninth of the initial volume i.e.

or

Substitute in equation (1),

The final pressure of the gas when its temperature returns to its initial value Pa.

50-60=10

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
