Polmon Vesnfer Interview Questions and Answers

Rate of heat transfer refers to the amount of heat energy transferred per unit of time.

• Rate of heat transfer is the rate at which heat energy is transferred from one object to another.

• It is measured in units such as watts or calories per second.

• The rate of heat transfer depends on factors such as the temperature difference between the objects, the surface area of contact, and the thermal conductivity of the materials i...read more

Latent heat is the heat absorbed or released by a substance during a change in its physical state without a change in temperature.

• Latent heat is the energy required to change the state of a substance without changing its temperature.

• It is absorbed during melting and vaporization and released during freezing and condensation.

• The amount of latent heat absorbed or released depends on the substance and the amount of it und...read more

Heat is a form of energy that is transferred between objects or systems due to temperature differences.

• Heat is the energy that flows from a hotter object to a cooler object.

• It is a result of the random motion of atoms and molecules.

• Heat can be transferred through conduction, convection, and radiation.

• Examples of heat include the warmth from the sun, the heat generated by a fire, and the heat transferred when boiling wa...read more
