Respuesta :

The correct answer to the question is B) Condensation.

EXPLANATION:

Before coming into any conclusion, first we have to understand various phase changes.

There are various phase changes in which matter in one state is converted into matter in another state.

Evaporation: Evaporation is the thermal process of state change in which a liquid is converted into corresponding vapor state.

For instance, water to steam or vapor.

Condensation: Condensation is just the opposite process of evaporation. In this process, a substance in vapor phase is converted into liquid phase.

For instance, water vapor to liquid water.

The two processes that is Convection and radiation mentioned in the question are not phase changes. These two are different modes of heat transfer between substances.

Hence, the process by which water vapor changes to a liquid is called condensation.

FURTHER EXPLANATION

Evaporation is the change in state from liquid to gas. This process requires an input of energy which will cause the particles to move faster and allow them to overcome the inter-particle attractions that are holding them together in the liquid state.

Condensation is the change in state from gas to liquid. In this case, energy is released and the particles start to move slowly and become unable to escape the inter-particle force of attraction that holds them as liquid.

Convection is the process of transferring heat through fluids in the form of convection currents. These form when there is a region that has a high temperature and a region where it is cooler. The particles at the hotter region move very quickly and collide frequently causing them to spread and occupy more space. This decreases the density and causes the particles to rise. On the other hand, the particles in the cooler region move slowly and do not collide as much. They move close to each other which increases the density and causes them to sink. This loop of particles in fluids rising and sinking is called convection current.

Radiation is another form of heat transfer. It is the transfer of thermal energy (in the form of infrared waves)  through air or vacuum. Heat is transferred between two objects without having to be in contact with each other.
