The answer is "thermal energy."
Answer: The starting pressure of is 1.39 atm.
Explanation:
Initial p 0 0
eq'm p-x 0 2x
Total pressure at equilibrium = p - x + 2x = p + x = 1.9...(1)
...(2)
Solving equation (1) and (2). we get x = 0.51
p + x = 1.9
p= 1.9 - 0.51 = 1.39 atm
The starting pressure of is 1.39 atm.
Formula of work done, W = - P (final volume - initial volume)
Here, W = work done
P = external pressure
External pressure is constant. In case of expansion final volume is greater than initial volume, therefore change in volume is positive.
W = negative ( positive )
W = negative
So, In case of expansion, the negative value of work indicates that the work is done by the system on the surrounding. Energy is released by system.
The sum of the forces of all of the molecules placing the wall divided by using the area of the wall is described to be the pressure. The pressure of a gasoline is then a measure of the common linear momentum of the moving molecules of a gas. The unit of pressure is pascal.

Hope this helps let know if does if not sorry :)
Answer:
The correct answer is option A.
Explanation:
Energy of the photon of an electromagnetic radiation is give by Planck's equation:
Where:
h = Planck's constant
c = speed of light
= Wavelength of the photon's radiation
Energy of photon of 800 nm monochromatic light
Energy per mole of photons:
..[1]
Energy of photon of 400 nm monochromatic light
Energy per mole of photons:
..[2]
[1] ÷ [2]
