Thermodynamics
In terms of de Broglie's hypothesis, what would be most indicative that matter exhibits wave-like properties?
Neutrons being absorbed by atomic nuclei without any scattering phenomenon.
Electrons producing diffraction patterns after passing through a crystal lattice.
Electrons traveling in straight-line paths between collisions in a vacuum tube.
Atoms only emitting specific quantized energies as photons when excited.
During an isothermal expansion of an ideal gas, what happens to the internal energy of the gas?
It increases due to work done on the gas.
It decreases as heat is removed from the gas.
It remains unchanged.
It decreases due to work done by the gas.
In which SI unit is moment of inertia measured?
Kilogram square meters
Meter
Pascal
Joule
In a Carnot cycle, why would the efficiency of a real heat engine be less than predicted when operating between two reservoirs at temperatures and ?
The actual temperatures of the reservoirs differ from and .
The materials used in constructing the engine cannot withstand the theoretical maximum efficiency.
Frictional losses and non-reversible processes prevent ideal conditions.
Heat is added to the system at a faster rate than it can be converted into work.
What is the basic SI unit for pressure?
Torr
Atmosphere
Bar
Pascal
What does the absence of diffraction patterns when large objects pass through slits suggest about wave-particle duality?
Quantum tunneling since large objects readily penetrate potential barriers with little probability of reflection.
Wave-like behavior because all objects possess some wavelength according to de Broglie's hypothesis.
Particle-like behavior because large objects cannot be quantized in energy levels like subatomic particles.
Large objects exhibit primarily particle-like behavior due to their significant mass relative to Planck's constant.
In a series RC (resistor-capacitor) circuit connected to a DC power source, how does adding another identical capacitor affect charging time for capacitors?
Charging time remains the same, effect capacitance is not changed involved circuitry.
Charging time halves, increased capacitance allows quicker charging.
Charging time increases fourfold, large capacitance extends charging duration to a much greater extent than predicted.
Charging time doubles, each capacitor stores equal amount charge slowing process down.

What does an increase in the temperature of a gas, while keeping volume constant, directly result in according to the kinetic theory of gases?
A change only in mass
No change in pressure
A decrease in pressure
An increase in pressure
How does a Carnot engine differ from real engines regarding efficiency?
Carnot engines perform less efficiently as they only operate between two specific temperatures extremes.
Real engines achieve higher efficiencies because they utilize multiple heat reservoirs simultaneously.
Carnot engines are theoretically maximum efficient whereas real engines always have lesser efficiency due to irreversibilities.
Both types have similar efficiencies but differ mainly in their operating processes and physical designs.
What unit of measure is used for force in physics?
Newton
Meter
Joule
Kilogram
