2. A sample of carbon dioxide occupies a volume of 5.50 L at 145 kPa. What pressure would the gas exert if the volume was decreased to 2.70L?
I

i think it's c. i'm not sure but i think so.

they are made of gases.

they have a spherical shape.

they make energy through fusion.

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.
