Answer #1

Convection

Convection is by far the most efficient and common way for heat to be transferred through liquids and gases. It occurs when some regions of a fluid get hotter than others, causing currents in the fluid that move it around to distribute that heat more evenly. Think of a house in the winter time. You may have noticed that the attic is always very warm while the basement is typically cool. This happens because when air heats up, it becomes light, causing it to move up towards the ceiling. Cold air is much heavier and falls to the floor. As the hot air moves to the ceiling and the cold air falls, these two types of air collide and mix, causing the heat from the warm arm to transfer to the cooler air and thus distributing the heat throughout the room.

For a body, the convection heat transfer coefficient to the adjacent air is 33 W/(m2.°C), and the radiative heat transfer coefficient from this body to another body is 36 W/(m2.°C). If the temperature of the first body and the adjacent air is 188 °C and 22 °C, respectively, determine the temperature of the second body so that the heat transferred by convection is equal in magnitude to the heat transferred by radiation

True or False? Convection is the movement of thermal energy through solids, liquids, and gasses by ordinary means. Temperature, heat, and motion are all forms of energy. Waves travel faster in water than in air. Radiation is the process of transferring heat from one material to another, by contact.
