The temperature of an ideal gas in a sealed 0.60 m3 container is reduced from 440 K to 270K. The final pressure of the gas is 40kPA. The molar heat capacity at constant volume of the gas is 28.0 J/mol * K. What is the work done by the gas?

zero

-51 kJ

-66 kJ

66 kJ

51 kJ

Ithink the answer is d i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you

Wavelength = pie*69+69 with ur mom

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.
