When energy is transferred to alr, what happens to the particles of alr?

They move faster.

Explanation:

Considering air as our system

When energy is transferred to air, the internal energy of the system increases and this affects the motion of the particles constituting air.

according to the equation.

k = boltzman's constant

T= absolute temperature in kelvin

Also, Kinetic energy

their velocity increases..

When the internal energy of the air particles increases, their temperature also increases.

This results in greater number of collisions between them and the sides of the container they are put in.

Hence, the pressure also increases, all these points indicate that particles of air move faster.

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.
