Answer:
a) W = - 9785.03 J
b) 9785.03 J is transferred to the environment.
Explanation:
n = 7.25 mol be the number of moles of the gas, T = 23.1 + 273 = 296.1 K be the temperature of the gas, Vf = 2.78 m^3 be the final volume of the gas, Vi = 4.81 m^3 be the volume of the gas.
a) The work done on compressing the gas is:
W = n×R×T×ln(Vf/Vi)
= (7.25)×(8.314)×(296.1)×ln(2.78/4.81)
W = - 9785.03 J
Therefore, the work done on compressing the gas is - 9785.03 J.
b) given the internal energy change is ΔEint vanishes when ΔT = 0, the heat transferred to the environment is found by considering the fact that from the first law of thermodynamics, Q = W = -9785.03 J so 9785.03 J is transferred to the environment.

<h2>Answer : </h2>
Newton's Third law of motion states :
" Every action has an equal and opposite reaction "
i.e If a force is applied by an object A on another object B then that object B also exerts a foce on object A, that is of same magnitude and opposite direction to the force applied by object A.
Ex - A book on a table exerts gravitational force on the table and table exerts back a normal force on the book.
