Answer:
45 minutes have passed
Step-by-step explanation:
1 degree = 1 minute
the slope of the line x=4 is undefined because x=4 is vertical line
The new pressure is 2 Kpa
<em><u>Solution:</u></em>
At constant temperature, the pressure of a sample of gas is inversely proportional to its volume
Therefore,
Let "p" be the pressure of sample gas
Let "v" be the volume
Then we get,
Where, "k" is the constant of proportionality
<em><u>I have some oxygen in a 2.28 liter container with a pressure of 5 kPa</u></em>
Substitute v = 2.28 and p = 5 in eqn 1
<em><u>I move all of it to a 5.7 liter container at the same temperature</u></em>
Substitute k = 11.4 and v = 5.7 in eqn 1
Thus new pressure is 2 kPa
-8 and 5: -8 x 5 = -40; -8 + 5 = -3
