What will happen if the pressure of the system is raised to 1.5 atmospheres and the temperature remains same? The piston will move upwards because the number of moles of the gas particles will increase.
The piston will move downwards because the gas particles will occupy less volume than before.
The piston will move upwards because the gas particles will hit the walls of the container with increased force.
The piston will move downwards because the gas particles will start moving randomly in all directions, pulling the piston down.

The piston will move downwards because the gas particles will occupy less volume than before.

Explanation:

Referring to Boyle's Law at constant temperature, the pressure P of a gas varies inversely with its volume V

                        PV = K

                        P =

                        P ∝

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
