2. A 5 year old child pushes with a force of 5 N to get a sumo wrestler to move, but the
Svetllana [295]

formula= W=f*d

w=work done

f=force

d=distance

w=f*d

w= 5n*0(does not budge)means does not move so distance is zero

w=5J

The work done by the children on the sumo wrestler is 5J

A gas is compressed from an initial volume of 5.55 L to a final volume of 1.22 L by an external pressure of 1.00 atm. During the
algol13

Answer:

Explanation:

change in the volume of the gas = 5.55 - 1.22

= 4.33 X 10⁻³ m³

external pressure ( constant ) P = 1 x 10⁵ Pa

work done on the gas

=external pressure x change in volume

= 10⁵ x  4.33 X 10⁻³

=4.33 x 10²

433 J

Using the formula

Q = ΔE + W , Q is heat added , ΔE is change in internal energy , W is work done by the gas

Given

Q = - 124 J ( heat is released so negative )

W = - 433 J . ( work done by gas is negative, because it is done on gas  )

- 124  = ΔE - 433

ΔE = 433  - 124

= 309 J

There is increase of 309 J in the internal energy of the gas.

In a given reversible process, the temperature of an ideal gas is kept constant as the gas is compressed to a smaller volume. Wh
sesenic [268]

Answer:

B. The gas must release heat to its surroundings.

Explanation:

Since the process is reversible , it must be slow . Since temperature is kept constant so the internal energy is constant , Since volume is decreased , pressure must be increased. Since work is done on the gas ( gas is compressed )  , so heat must be released by the gas so that its internal energy remains constant.
