A container is filled with a gas. The container has a wall controlled by a moveable piston. The
ioda

Answer:

The new volume will be 3.67 L.

Explanation:

As the volume increases, the gas particles (atoms or molecules) take longer to reach the walls of the container and therefore collide with them fewer times per unit of time. This means that the pressure will be lower because it represents the frequency of collisions of the gas against the walls. In this way pressure and volume are related, determining Boyle's law which says:

"The volume occupied by a certain gaseous mass at constant temperature is inversely proportional to pressure"

Boyle's law is expressed mathematically as:

P*V=k

Now it is possible to assume that you have a certain volume of gas V1 that is at a pressure P1 at the beginning of the experiment. If you vary the volume of gas to a new value V2, then the pressure will change to P2, and it will be fulfilled:

P1 * V1 = P2 * V2

In this case:

  • P1= 1.85 atm
  • V1= 4.64 L
  • P2= 2.34 atm
  • V2= ?

Replacing:

1.85 atm* 4.64 L= 2.34 atm* V2

Solving:

V2= \frac{1.85 atm* 4.64 L}{2.34 atm}

V2= 3.67 L

<u><em>The new volume will be 3.67 L.</em></u>

Which of the following forces is responsible for accretion?
Makovka662 [10]

Answer:

It's explained by nebular theory, which describes the forces and processes at play as a nebula spins and accretes into a star and its planets orbiting it. A key piece of information to always keep in mind is that the force of gravity is responsible for accretion and all the objects it forms.

How many neutrons are in the nucleus of an atom with an atomic number of 25
Makovka662 [10]

Answer:

The neutron is 30

Explanation:

The element with atomic number of 25 is Manganese. it has a mass number of approximately 55.

Therefore, the neutron number = Mass number - Proton number (i.e. atomic number)

                                         = 55 - 25

  Neutron number            = 30
