PVL2602 MCQ EXAM PACK 2026 MASTER
EXAMINATION TEST
◉ heat. Answer: The energy transferred between objects that are at
different temperatures
◉ Zeroth Law of Thermodynamics. Answer: A law that if two
systems are separately found to be in thermal equilibrium with a
third system, the first two systems are in thermal equilibrium with
each other; that is, all three systems are at the same temperature.
Also known as thermodynamic equilibrium.
◉ (U) kinetics. Answer: internal energy
◉ what does W<0 imply?. Answer: System is doing work; work done
by system
◉ What does w>0 mean?. Answer: System is receiving work; work
done on the system
◉ what does q<0 imply?. Answer: heat is flowing out of the system;
system is lowing heat
,◉ what does q>0 imply?. Answer: heat is flowing into the system;
system is gaining heat
◉ delta U equation. Answer: delta U=q+w
◉ sign of delta U, q=0 work done by the system. Answer: negative
◉ sign of delta U, q=0, work done on the system. Answer: positive
◉ sign of delta U, w=0, heat flowing out of a system. Answer:
negative
◉ sign of delta U, w=0, heat flowing into a system. Answer: positive
◉ Joule to Calorie Conversion. Answer: 1 cal = 4.184 J
◉ pressure-volume work. Answer: the work that occurs when a
volume change takes place against an external pressure
◉ P-V work equation. Answer: =-P(ext)dV
, ◉ how to determine change in volume from balanced equation.
Answer: delta V is proportional to change in the number of gaseous
moles
◉ state function. Answer: property that only depends on the current
state of the system; independent of the path it takes to get there
◉ is work (W) a state function?. Answer: No, work is NOT a state
function
◉ is heat (q) a state function?. Answer: No, heat is not a state
function
◉ what does Qp (subscript) mean?. Answer: constant pressure
◉ heat capacity (C). Answer: amount of heat required to change the
temperature of the system by 1K
◉ specific heat capacity (c). Answer: amount of that required to
change the temperature of 1 g of a substance by 1K
◉ Molar heat capacity (Cm). Answer: amount of heat required to
change the temperature of 1 mol of a substance by 1K
