What term is used to describe the lowest energy level of a particle?
coldgirl [10]

Answer:

Ground state

Explanation:

Ground state is the lowest energy level of particle. In this state toms are stable.

When transition occur from lower energy level to higher energy level require a gain of energy. Electron could not jump into higher energy level without gaining thew energy.

When electron jump into lower energy level from high energy level it loses the energy.

The process is called excitation and de-excitation.

Excitation:

When the energy is provided to the atom the electrons by absorbing the energy jump to the higher energy levels. This process is called excitation. The amount of energy absorbed by the electron is exactly equal to the energy difference of orbits.

De-excitation:

When the excited electron fall back to the lower energy levels the energy is released in the form of radiations. this energy is exactly equal to the energy difference between the orbits. The characteristics bright colors are due to the these emitted radiations. These emitted radiations can be seen if they are fall in the visible region of spectrum.

3. Name the apparatus you would use to measure :<br><br> 87 cm of Carbon Dioxide
Ksivusya [100]

Answer:

The volume of carbon dioxide gas produced can be measured using a gas syringe.

Explanation:

gas jar

Carbon dioxide is slightly soluble in water and denser than air, so another way to collect it is in a dry, upright gas jar. As the carbon dioxide falls out of the delivery tube and into the gas jar, it pushes the less dense air out of the top of the gas jar.
