At 25oC three moles of a gas occupy a volume of 4.0 L at 1.9 kPa If the volume increases to 8.0 L what will the new pressure be?

Answers

Answer 1

Answer:

0.95 kPa

Explanation:

[tex]P_{1} V_{1} = P_{2}V_{2}[/tex]

(4.0)(1.9) = ([tex]P_{2}[/tex])(8.0)

[tex]P_{2}= 0.95[/tex] kPa

-- However, you should see that when the volume increases (doubles, in this case) you will divide the original pressure value by 2. Pressure and volume are inversely related.

Answer 2

Answer:

0.95kPa

Explanation:

I've just answered this question and it came out right.

Which of the following best summarizes the way in which the development of the factory system and the development of new transportation infrastructure such as railways worked together as factors facilitating British industrialization? The factory system produced the surplus labor that led large numbers of British people to emigrate overseas, and the new transportation infrastructure enabled those migrants to make their journeys. A The factory system concentrated the working classes in cities, and new transportation infrastructure allowed governments to better monitor and police these workers. B The factory system concentrated production in relatively few locations, and the new transportation infrastructure allowed more goods and people to reach these locations in less time.
