Question

question 4 (10 points)
law of energy conservation applied to a thermal system is known as:
o a thermal resistance of a material (r-value)
o b coefficient of heat conductivity (u-value)
o c 1st law of thermodynamics
o d 2nd law of thermodynamics

Explanation:

The first law of thermodynamics states that energy can neither be created nor destroyed, only transferred or converted. This is the application of the law of energy conservation to a thermal system.

• Thermal Resistance (R - Value) measures a material's resistance to heat flow.
• Coefficient of Heat Conductivity (U - Value) measures a material's ability to conduct heat.
• The second law of thermodynamics deals with entropy and the direction of heat flow.

Answer:

C. 1st Law of Thermodynamics
