In what way boiling & condensation differs from other types of heat exchange?

Boiling and condensation differ from other forms of convection in that they depend on the latent heat of vaporization, which is very high for common pressures, therefore large amounts of heat can be transferred during boiling and condensation essentially at constant temperature.

Is condensing the same as melting?

Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.

How are evaporation and condensation the same?

The terms evaporation and condensation are both steps in the water cycle. Evaporation occurs when a liquid (water in the water cycle) is heated and changes from a liquid to a gas. Condensation occurs when water vapor cools and changes from a gas to a liquid.

What are the applications of boiling?

The primary purpose of early industrial applications of boiling was to generate steam for transportation and power. Today’s power industry still takes advantage of the high heat transfer rates typical of boiling to extract energy from solar, fossil, and nuclear fuels.

What is process of condensation?

Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.

Is the process which involves boiling followed by condensation?

condensation. The changing of water into water vapours on heating is for evaporation or boiling. The changing of water vapours into liquid water on cooling is called condensation. Distillation involves two processes evaporation followed by condensation.

What is melting and boiling?

melting point is the temperature at which a solid changes into a liquid. boiling point is the temperature at which a liquid changes into a gas.

What is the difference between boiling and condensation?

Boiling and Condensation (You Are Here!) Boiling is the change of state from a liquid to a gas. Boiling of a pure substance occurs at a particular constant temperature called boiling point. The change of state from a gas to a liquid is called condensation. A pure substance condenses at a temperature equal to its boiling point.

What happens to the temperature of a liquid when it is boiling?

Temperature remains constant at 100∘C as the liquid is boiling During the boiling process, liquid and gas exist in equilibrium. Step by step of what happens during boiling: Heat energy is absorbed by the particles The kinetic energy of the particles increases At boiling point, the particles have enough energy…

When does condensation of a pure substance occur?

Boiling of a pure substance occurs at a particular constant temperature called boiling point. The change of state from a gas to a liquid is called condensation. A pure substance condenses at a temperature equal to its boiling point.

How is condensation of a gas into a liquid?

Condensation is the conversion of a substance (such as water) from the vapor state to a denser liquid or solid state, usually initiated by a reduction in temperature of the vapor. Hence, it is the change of phase of matter from gas to liquid phase.
