A gas is contained in a thick-walled balloon. When the pressure changes from 39.1 bar to 87.0 bar the volume changes from blank
lidiya [134]

Answer: -

1.34 L

Explanation: -

Initial Pressure P 1 = 39.1 bar

Initial Temperature T 1 = 643 K

Let the initial volume be V 1.

Final pressure P 2 = 87.0 bar

Final temperature T 2 = 525 K.

Final volume V 2 = 0.492 L

Using the equation

\frac{P1 V 1}{T1} = \frac{P 2 V 2}{T2}

V 1 = \frac{P2 V2 T1}{P 1 T2}

Plugging in the values

We have

V 1 = 87 bar x 0.492 L x 643 K / (39.1 bar x 525 K)

= 1.34 L

Thus, a gas is contained in a thick-walled balloon. When the pressure changes from 39.1 bar to 87.0 bar the volume changes from 1.34 L to 0.492L and the temperature changes from 643K to 525K

How many miles are in 0.062500 light seconds (s)?
MrRa [10]

Answer:

11625 miles

Explanation:

A second of light is the distance that light travels in a second. It has a value of 299792458 kilometers or if we do the unit conversion, 186,000 miles. A mile is 1.609 kilometers

Let's make a rule of three:

1 light s travels a distance of 186000 miles

0.062500 light s would travel a distance of (0.062500 . 186000) = 11625 miles
