Thermal Properties Flashcards
What are conductors?
Conductors are materials that can conduct heat well.
What are some examples of conductors?
Metals are good conductors. Ex: silver, gold, etc.
What are insulators?
Insulators are materials that don’t conduct heat well.
What are some examples of insulators?
Wood, air, and wool are good insulators.
What is density?
Density is the mass per unit volume
How do you calculate density?
p = m/v
What is the SI Unit of density?
kg/m to the power of 3
What are the four main changes of phase?
Melting, freezing, vaporization, and condensation
What is latent heat?
The heat absorbed or released at constant temperature during a change of phase is latent heat.
What is latent heat of fusion?
The latent heat of fusion is the amount of heat requited to change the phase of 1kg of the substance from solid to liquid or vice versa. The unit is J/kg.
What is the formula for latent heat of fusion
Q = m x Hf
What is latent heat of vaporization?
The latent heat of vaporization is the amount of heat required to change the phase of hg of a substance from liquid ot gas or vice versa. The unit is J/kg.
What is the formula for latent heat of vaporization?
Q = m x Hv
What is the latent heat of fusion of water?
334 (kJ/kg)
What is the specific heat of water?
4.18
