Answer:
3. Charge on an electron
Explanation:
Millikan and Fletcher could measure the charge on the oil droplets.
When they repeated the oil drop experiment many times, they found that the charges were integral multiples of 1.59 × 10⁻¹⁹ C.
They proposed that this was the charge on an electron.
I think that the answer might be A) 1.5 L of NH3(g)
<u>Answer:</u> The correct answer is temperature of the gas.
<u>Explanation:</u>
Average kinetic energy of the particles is defined as the average of the kinetic energies of all the particles in a gas molecule. The equation used to calculate the average kinetic energy of a gas is given by:
where,
K = kinetic energy of the gas
R = gas constant
T = temperature of the gas
= Avogadro's number
From the above equation, kinetic energy is directly related to the temperature of the gas molecule. As, the temperature of the gas increases, kinetic energy also increases and vice-versa.
Hence, the correct answer is temperature of the gas.
