1.
An air bubble released from the bottom of a deep lake expands in volume as it rises towards the surface because:
The bubble absorbs water molecules into its gas phase
Atmospheric pressure increases at the surface
The water temperature at the surface is near absolute zero
The hydrostatic pressure decreases as depth decreases, allowing the trapped air to expand according to Boyle's law
2.
The slope of the straight line obtained by plotting maximum kinetic energy of photoelectrons against the frequency of incident light represents:
B) Speed of light in vacuum
C) Planck's constant (\(h\))
D) Charge of the electron (\(e\))
A) Work function of the metal
