A gas is expanded from an initial volume of 1 L at 1 atm at 7 °C to a final volume of 5 L. During the expansion the gas increases to 287 °C. What is the final pressure?

0.40 atm

Explanation:

To answer this problem we can use the combined gas law:

In this case:

We input the data:

And solve for P₂:

c. is the answer

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
