If you start with a substance as a solid, what will happen to the molecules as you add thermal energy (heat)?
AveGali [126]

Answer:

C. molecules speed up as more thermal energy is added

Explanation:

The molecules will simply speed up as more thermal energy is added to the solid.

Thermal energy is a form of kinetic energy which is set in motion.

  • Heat causes kinetic energy build up in a body.
  • As the molecules of the solid gains heat, they will continue to increase in thermal energy.
  • They are forced to start vibrating about their fixed point.
  • Thereafter, when they have enough energy, they break free from the forces holding them.
  • Therefore, they move from a state of rest to one with a very high kinetic energy where the molecules moves rapidly.
  • This is why a solid will change to liquid and sometimes eventually gas

Which equation was used by Albert Einstein to explain the photoelectric effect? [E = energy, h = Planck’s constant, and v = freq
Afina-wow [57]

Answer:

E = hv

Explanation:

  • The photoelectric effect is a phenomenon when the electromagnetic waves of a particular wavelength strike on the metal plate like zinc, it ejects the free electrons.
  • The ejected electrons have the kinetic energy and this energy is responsible for the electric energy.
  • The kinetic energy of the emitted electrons is linked with the frequency of the incident rays.
  • If the rays hitting the metal plate is below the minimum required threshold value, the photoelectrons are not ejected.
  • The photoelectric equation is given by

                            E = hν - ∅

Where, ∅ is the minimum energy required to remove an electron.

At a temperature of 320K, the gas in a cylinder has a volume of 40.0 liters. If the volume of the gas is decreased to 20.0 liter
Lerok [7]
Assuming the gas behaves ideally,
PV/T = constant. P will also be constant in this giving us:
V₁/T₁ = V₂/T₂
40/320 = 20/T₂
T₂ = 160 K
The answer is A.
