Answer:
Gay Lussac law
Explanation:
Gay Lussac law states that for a gas kept at constant volume (so, in a rigid container), the pressure of the gas is directly proportional to the absolute temperature.
In mathematical formula:
where
p is the gas pressure
T is the absolute temperature
According to this law, we see therefore that if the absolute temperature of the gas is doubled:
T' = 2T
The pressure will also double:
Answer:
The charge stored in a parallel plate capacitor is proportional to the potential, and capacitance across the plates.
Explanation:
The capacitance of a parallel plate capacitor is given by:
where
Q is the charge stored
V is the potential difference across the capacitor
Re-arranging the formula, we get
From this expression, we see that the charge stored (Q) is proportional to both the potential (V) and the capacitance (C).
Answer:
3.5434 eV
Explanation:
For a particle with kinetic energy E and mass m , the wavelength associated is given by the following relation,
E =
Putting the values we get
E =
=1.063 x 10⁻²¹ J
= .0066 eV.
Energy of¹light in terms of eV
= 1244 / 350 = 3.55 eV.
Work function = 3.55 - 0.0066 = 3.5434 eV.
