A gas is compressed in a cylinder from a volume of 20.0 l to 2.0 l by a constant pressure of 10.0 atm. calculate the amount of w
ork done on the system.
1 answer:
First, we need to convert the pressure in SI units. Keeping in mind that
:
The initial and final volume of the gas are (keeping in mind that
):
So, the work done on the gas by the surrounding is
And the final positive sign means that this work corresponds to an increase in internal energy of the gas.

Answer:
Average force = 67 mn
Explanation:
Given:
Initial velocity u = 0 m/s
Final velocity v = 67 m/s
Time t = 1 ms = 0.001 sec.
Computation:
Using Momentum theory
Change in momentum = F × Δt
(v-u)/t = F × Δt
F × 0.001 = (67 - 0)/0.001
F= 67,000,000
Average force = 67 mn
