Thermodynamics
What physical quantity is directly proportional to the temperature of a system in thermal equilibrium?
Average kinetic energy of particles
Mass of the system
Volume of the system
Total potential energy of particles
Which quantity remains constant in an isobaric process?
Volume
Temperature
Entropy
Pressure
If a thermodynamic system consisting of diatomic molecules absorbs photons with enough energy to excite rotational degrees of freedom but not vibrational modes, how does this affect specific heat capacity at constant volume?
It decreases due to increased radiative losses from these excited rotational states returning back to ground state emitting photons.
It increases because additional degrees of freedom become accessible for distributing thermal energy.
It remains unchanged since only electronic excitations significantly alter specific heats at room temperature conditions.
It becomes variable depending on ambient pressure as photon absorption changes with pressure variations around diatomic molecules.
During which type of thermodynamic process does no exchange of heat occur between a system and its surroundings?
Isothermal
Adiabatic
Isometric
Isochoric
What is the zeroth law of thermodynamics primarily concerned with?
Entropy change in a system
Conservation of energy
Work done by heat engines
Thermal equilibrium
What phenomenon can be explained by both wave and particle theories of light?
The constant speed of light in a vacuum regardless of the motion of the source or observer.
The specific quantized energy levels within an atom's electron cloud.
The emission spectrum produced by excited gas atoms returning to lower energy states.
Diffraction patterns resulting from light passing through double slits.
When a closed system undergoes an adiabatic process that compresses its gas, how does this affect the temperature of the gas?
The temperature decreases.
The temperature first decreases then increases completing a cycle.
The temperature remains constant.
The temperature increases.

If gravitational force became inversely proportional to distance rather than distance squared, how would this modify heat transfer through convection currents within Earth's atmosphere?
There will be no convective current formation because gravity being non-inverse square eliminates all buoyant forces essential for initiating these currents.
Heat transfer efficiency via convection currents increases as weaker gravity enhances fluid displacement upwards causing faster convective motion.
Heat transfer efficiency via convection currents remains unaffected as convection relies solely on thermal gradients and fluid properties unaffected by gravity changes.
Heat transfer efficiency via convection currents would decrease due to altered buoyancy forces resulting from changes in gravitational interactions with mass distributions.
If entropy is viewed as a measure of disorder within a thermodynamic system, how does entropy typically change when a liquid turns into a vapor?
Entropy decreases because vapors have less freedom of movement than liquids.
Entropy stays the same because total energy doesn't change.
Entropy increases.
Entropy oscillates before settling back to its original state post-transition.
How does increasing temperature impact conductivity while considering both electrolytic and metallic conductors?
Decreases conductivity for both types due to reduced mean free path length for charge carriers.
Increases metallic conductivity by providing more free electrons while having no effect on electrolytes.
Increases conductivity for electrolytes due to enhanced ion mobility; tends to decrease metallic conductivity due to increased electron scattering.
Has varied effects depending on material but generally enhances conductivity aggregately across both conductor types.
