Verified Answer
In thermodynamic process pressure of a fixed mass of gas is changed in...
ΔQ = –30J
Δw = –18
Ui = 60 J
Uf = ?
ΔQ = Δw + Uf – Ui
–30 = –18 + Uf – 60 ⇒ Uf = 48 J
Δw = –18
Ui = 60 J
Uf = ?
ΔQ = Δw + Uf – Ui
–30 = –18 + Uf – 60 ⇒ Uf = 48 J

In thermodynamic process pressure of a fixed mass of gas is changed in...
Given data:
Initial internal energy (Ui) = 60 Joules
Heat released (Q) = -30 Joules (negative sign indicates heat is released)
Work done (W) = -18 Joules (negative sign indicates work is done on the gas)
Solution:
The change in internal energy (ΔU) of a system is given by the sum of heat and work done on the system, i.e., ΔU = Q + W.
Substituting the given values:
ΔU = -30 + (-18)
ΔU = -48 Joules
The final internal energy (Uf) can be calculated using the formula Uf = Ui + ΔU.
Substituting the values:
Uf = 60 + (-48)
Uf = 12 Joules
However, the answer given is 48 Joules. This implies that there may be a typo or mistake in the given question or answer choices. It is always important to cross-check the given information and verify the calculations to ensure the accuracy of the answer.
