Thermodynamics
In an adiabatic process for an ideal gas, which quantity remains constant?
Heat transfer is zero
Temperature always increases
Pressure stays constant throughout the process
Volume remains unchanged
Assuming Avogadro's number was reduced by half, what impact would this have on the molar heat capacity at constant volume for an ideal monatomic gas?
It could not be determined without additional information about molecular weights.
It would be halved.
It would remain unchanged.
It would double.
If a proton enters a region with both an electric and a uniform magnetic field perpendicularly, what would be the expected trajectory?
Parabolic due to the combined effects of electricity and magnetism on charged particles.
Straight line since balanced forces neutralize motion totally.
Helical with axis parallel to either field depending on the stronger one's influence.
What is the standard SI unit used to measure work done by or on a system?
Kilogram meter squared over seconds squared (kg.m^2/s^2)
Watt second (Ws)
Newton meter (Nm)
Pascal (Pa)
How would an increase in the electric constant affect the energy density of the electromagnetic field stored within an ideal capacitor charged to a fixed potential difference?
The energy density would be reduced by half.
The energy density would increase by a factor of four.
The energy density would not change.
The energy density could double.
Which quantity remains unchanged for an ideal gas undergoing an isothermal process?
Volume
Pressure
Temperature
Internal Energy
If Planck's constant were doubled, how would the energy of a photon emitted during an electronic transition in a hydrogen atom change?
It would be halved.
It would remain the same.
It would quadruple.
It would double.

What is the SI unit of temperature?
Joule (J)
Kelvin (K)
Fahrenheit (°F)
Celsius (°C)
Why do real gases deviate from ideal behavior at high pressures?
The gases ionize forming plasma at high pressures
They exhibit intermolecular attractions that affect their behavior
Their molecules occupy significant volume compared to available space
High pressures induce nuclear fusion reactions within gas molecules
