One Dimensional Steady State Heat Conduction

What is Fourier's Law of Heat Conduction?

• The law states that the rate of heat transfer is proportional to the negative gradient of the temperature and the area through which the heat is being transferred.

• The law states that the rate of heat transfer is inversely proportional to the area through which the heat is being transferred.

• The law states that the rate of heat transfer is not affected by the temperature gradient.

• The law states that the rate of heat transfer is proportional to the positive gradient of the temperature and the area through which the heat is being transferred.

Define Thermal Conductivity.

• Thermal conductivity is the ability of a material to resist heat.

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

• Thermal conductivity is the ability of a material to generate heat.

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

What is the Heat Transfer Equation for one dimensional steady state conduction?

• Q = hA(T2-T1)

• Q = -kA(dT/dx)

• Q = mcΔT

• Q = σεA(T2^4-T1^4)

Name two common insulation materials used to reduce heat transfer.

Explain the process of conduction in solids.

• Conduction in solids is the process of heat transfer through radiation

• Conduction in solids is the process of heat transfer through fluid movement

• Conduction in solids is the process of heat transfer through electromagnetic waves

• Conduction in solids is the process of heat transfer through direct contact between particles, where kinetic energy is transferred from one particle to another through collisions.
