Explanation:
Internal energy is the sum of all the energies inside or within a system because molecules of the system will have kinetic, potential, rotational, vibrational etc energies.
Internal energy arises because of random or disordered movement of particles within a system.
Therefore, internal energy of a system is the sum of kinetic and potential energy of all the particles present inside the system.
The variable for internal energy is "U". Also, change in internal energy is represented by .

(Its correct, I just took a quiz and it is the right answer. hope I helped.)
1 atm=7.15/9.25
Volume increase comes from reduced pressure
2.04 atm is the pressure of the nitrogen gas in the container when 0.316 mol sample of nitrogen gas, N2 (g), is placed in a 4.00 L container at 315 K.
Explanation:
Data given:
moles of nitrogen gas, n = 0.316
volume of the nitrogen gas, V = 4 litres
temperature of the container of nitrogen gas = 315 K
R (gas constant) = 0.08201 Latm/mole K
Pressure of the nitrogen gas on the container, P = ?
from the data given, we will apply ideal gas law equation to calculate the pressure on the nitrogen gas:
PV = nRT
Rearranging the equation,
P =
P =
P = 2.04 atm
The pressure of the nitrogen gas in the container is 2.04 atm.
Answer:
That substance is an element.
Explanation:
Atoms in a substance have the same identity, that substance is an element. in other words if all atoms are alike then it is an element.
Ive gotten this question asked to me before.
