The correct option is D.
Fusion and fission reactions involve the generation of energy either by the coming together of atomic nuclei or by splitting apart of atomic nuclei. The amount of energy that is generated during fusion and fission process is very high and is in the range of kiloelectron volts (10^3 eV), megaelectron volts (10^6 eV) and gigaelectron volts (10^9 eV) per atom or particle.

If i initially have 4.0 l of a gas at a pressure of 1.1 atm, what will the volume be if i increase the pressure of 3.4 atm?

ddd [48]

The volume of a gas that its pressure increase to 3.4 atm is calculated as follows

By use of boyles law that is P1V1=P2V2
V1=4.0 L
P1=1.1 atm
P2=3.4 atm
V2= P1V1/P2

(1.1 atm x 4.0 L)/3.4 atm= 1.29 L

1.905 moles of Helium gas are in the tube. Hence, option A is correct.

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Calculate the moles of the gas using the gas law,

PV=nRT, where n is the moles and R is the gas constant. Then divide the given mass by the number of moles to get molar mass.

Given data:

P= 4.972 atm

V= 9.583 L

R= $0.082057338 \;L \;atm \;K^{-1}mol^{-1}$
