Answer:
Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. ... The fire's heat causes molecules in the pan to vibrate faster, making it hotter. These vibrating molecules collide with their neighboring molecules, making them also vibrate faster.
Explanation:
Answer:
Explanation:
Hello, in this case, the lead is catching heat and the water losing it, that's why the heat relation ship is (D is for Δ):
Now, by stating the heat capacity definition:
Solving for the equilibrium temperature:
Which is very close to the water's temperature since the lead's both mass and head capacity are lower than those for water.
Best regards.
The kinetic energy that the liberated electron has in eV based on the given values is :
10.28 eV.
<h3>Explanation:</h3>
- 1 eV is the kinetic energy gained by an electron or proton when acted upon by a 1 volt potential difference. E = QV is the formula for energy in terms of charge and potential difference.
A photoelectron's maximum kinetic energy is given by
Emax = hf - W
- where h is Plank's constant,
- f is the incident photon's frequency, and
- W denotes the metal surface's work function.
here given,
f = 3.62 x 10¹⁵ Hz
W = 4.70 eV
by recalling the equation for a photoelectron's maximum kinetic energy with given values,
Emax = hf - W
= ((4.14 × 10⁻¹⁵eV.s)(3.62 x 10¹⁵ Hz)) - (4.70 eV)
= 10.28 eV
As a result, we discovered that the maximum kinetic energy of electrons is 10.28eV.
