Answer:
The final volume is 320 mL at pressure of 100 kPa.
Step-by-step explanation:
Boyle's law gives the relation between volume and pressure of a gas. It states that at constant temperature, volume is inversely proportional to its pressure such that,
Let
We need to find 
. Using above equation, we get :
So, the final volume is 320 mL at pressure of 100 kPa.
Answer:
Step-by-step explanation:
<u>Answer:</u>
45
<u>Step-by-step explanation:</u>
We are given an equation <em>x - y = 30 </em>which we are to solve for x when the value of y is 15.
To solve this linear equation for x, we just need to substitute the given value of y into the equation to get the value of x.
x - y = 30
x - 15 = 30
x = 30 + 15
x = 45
Therefore, the value of x is 45 when y = 30.
Unfortunately this value is not in the given options but 45 is the correct answer.
