N an adiabatic process, what happens when gases in a system are compressed?
den301095 [7]
When a gas is compressed rapidly, temperature increases because temperature and volume of gas are inversely proportional to each other according to gas laws. When a gas is compressed rapidly, its volume decreases leading to increase in temperature.
Also the pressure increase which also increases the randomness of the gas molecules which start to collide more frequently and thus the temperature rises .
just to make you understand what randomness affects - you would have noticed that you often sweat in a small room filled with people but it’s cooler if the same number of people are there in a bigger room.
hope it helps you

35. A spherical conductor has a radius of 14.0 cm and a charge of 26.0 mC. Calculate the electric field and the electric poten-
bulgar [2K]

Answer:

Therefore,

V_{10}=2.34\times 10^{6}\ V

V_{20}=1.17\times 10^{6}\ V

V_{14}=1.67\times 10^{6}\ V

Explanation:

Given:

A spherical conductor has a radius of 14.0 cm

Q = 26.0 μC ( Assume it to be microC in the question it is miliC )

To Find:

Electric potential at

(a) r 5 10.0 cm, (b) r 5 20.0 cm, and (c) r 5 14.0 cm from the center.

Solution:

Electric potential due to point charge Q at any distance r from the charge is,

V=\dfrac{kQ}{r}

Where,

V = Electric Potential

k = Coulombs constant = 9 × 10⁹ Nm²/C².

Q = Charge

r = distance in meter

Substituting the values we get

At r = 10 cm = 0.1 m

V=\dfrac{9\times 10^{9}\times 26\times 10^{-6}}{0.1}

V=2.34\times 10^{6}\ V

At r = 20 cm = 0.2 m

V=\dfrac{9\times 10^{9}\times 26\times 10^{-6}}{0.2}

V=1.17\times 10^{6}\ V

At r = 14 cm = 0.14 m

V=\dfrac{9\times 10^{9}\times 26\times 10^{-6}}{0.14}

V=1.67\times 10^{6}\ V

Therefore,

V_{10}=2.34\times 10^{6}\ V

V_{20}=1.17\times 10^{6}\ V

V_{14}=1.67\times 10^{6}\ V
