Frequently Asked Questions
What is specific heat capacity?
Specific heat capacity is the amount of heat energy required to raise the temperature of one kilogram of a substance by one degree Kelvin. Water has a high specific heat capacity of 4186 J/kg⋅K, making it excellent for thermal storage.
How does thermal conductivity affect heat transfer?
Higher thermal conductivity means heat transfers more easily through the material. Metals like copper (400 W/m⋅K) conduct heat well, while insulators like wood (0.1 W/m⋅K) resist heat flow.
What's the difference between conduction and convection?
Conduction is heat transfer through direct contact between molecules, while convection involves heat transfer through fluid motion. This calculator focuses on conduction and sensible heat changes in materials.
