Plane and Composite Systems for Heat Transfer

What is the primary mechanism of heat transfer in solids?

• Heat transfer through the movement of liquid particles within a solid material.

• Heat transfer through the conversion of solid particles into gas within a material.

• Heat transfer through electromagnetic waves in solids.

• Heat transfer through direct contact between particles or atoms within a solid material.

What is the primary mechanism of heat transfer in fluids?

• Heat transfer in fluids occurs through radiation

• Heat transfer in fluids occurs through the expansion and contraction of the fluid

• Heat transfer in fluids occurs through solid particles moving within the fluid

• Heat transfer in fluids occurs through the movement of the fluid itself, where warmer fluid rises and cooler fluid sinks, creating a circular motion that transfers heat.

What is the definition of thermal conductivity?

• Thermal conductivity is the property of a material to conduct heat.

• Thermal conductivity is the ability of a material to conduct electricity.

What are some commonly used materials for insulating against heat transfer?

• paper

• cotton balls

• aluminum foil

• fiberglass, mineral wool, cellulose, foam board, spray foam

What are the primary methods of heat transfer in composite systems?

• Heat transfer in composite systems occurs through conduction, convection, and radiation.

• Heat transfer in composite systems occurs through photosynthesis

• Heat transfer in composite systems occurs through magnetism

• Heat transfer in composite systems occurs through evaporation
