Diffraction pattern disappears replaced by single-slit diffraction
Alternate bright/dark fringes get enhanced clarity
Light stops passing through completely
Double-slit interference pattern stays unchanged

What type of thermal transfer occurs primarily through mass movement within fluids (gases or liquids)?
Convection
Radiation
Adiabatic expansion
Conduction
What is the SI unit for pressure?
Bar
Atmosphere
Torr
Pascal
When an ideal gas expands at constant pressure, what is the work done by the gas equal to?
Work (W) equals Pressure (P) times Change in Volume (ΔV)
Work (W) equals Change in Kinetic Energy (ΔKE)
Work (W) equals Change in Volume (ΔV) divided by Pressure (P)
Work (W) equals Force (F) times Distance (d)
In a Carnot engine operating between two reservoirs, what effect would decreasing the cold reservoir's temperature have on efficiency?
Efficiency would remain unchanged because it depends only on hot reservoir's temperature.
The engine would cease to function as it violates the second law of thermodynamics.
Efficiency would decrease.
Efficiency would increase.

What is the typical effect on the internal energy of a substance when it undergoes an increase in temperature?
The substance undergoes a phase change.
The internal energy remains constant.
The internal energy decreases.
The internal energy increases.
What type of heat transfer occurs when warmth from sunlight heats up your skin directly without heating up the air in between significantly?
Condensation
Radiation
Compression
Convection
If you double both the mass and absolute temperature (in Kelvin) of an object but keep its specific heat capacity unchanged, how does this affect its thermal energy content?
It increases by a factor of eight as both doubling factors are considered exponentially.
It doubles only as temperature has a greater effect on the thermal energy than mass does.
It remains unchanged since the increase in temperature is offset by proportional increase in mass.
It quadruples because thermal energy depends directly on both mass and temperature.
