Question

A fixed mass of gas in a thermally insulated container is compressed . after compression the temperarure of gas will have?
A. Fallen, scince more molecules bombarded the container and so they must be moving slower
B.Fallen, since mor molecules collide more frequently with one another and so their average speed is lower
C.remained constant if the compression is very slow
D.Risen, since doing work on the gas increases the kinetic energy of the molecules
E.Risen, sinc there are more intermolecula sollisions and so more heat is produced them

Kindly give me right answer and hurry up..​

Answer 1

Answer:

ANSWER

If an ideal gas is compressed adiabatically, its temperature rises, because heat produced cannot be lost to the surroundings. Each molecule has more KE than before because of collisions of molecules with moving parts of the wall(i.e., piston compressing the gas).

Answer 2

Answer:

right option is:

Explanation:

D.Risen, since doing work on the gas increases the kinetic energy of the molecules
