Boyle's law says that the volume occupied by a given gaseous mass at constant temperature is inversely proportional to pressure. That is: if the pressure increases, the volume decreases, while if the pressure decreases, the volume increases. This is expressed mathematically as the product of pressure times volume equal to a constant value:

P*V=k

Assuming a certain volume of gas V1 that is at a pressure P1 at the beginning of the experiment, by varying 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= 2.14 atm
V1= 3 L
P2= ?
V2= 8.15 L

Replacing:

2.14 atm*3 L= P2* 8.15 L

Solving:

$\frac{2.14 atm*3 L}{8.15 L} =P2$

0.788 atm= P2

The final pressure is 0.788 atm (option b).

Explain the connection between atoms and electricity

zaharov [31]

Answer:

The protons and electrons of an atom are attracted to each other. They both carry an electrical charge. Protons have a positive charge (+) and electrons have a negative charge (-). The positive charge of the protons is equal to the negative charge of the electrons.
