Physical Properties Flashcards
Define physical properties.
The properties wich aren’t concerned with the application of force to a body.
Give reason/High density is considered double-edged weapon?🤔
It’s advantage when we casting 😬 but disadvantage in denture base🫓.
Why prolonged heat of metals is NOT NECESSARY?
Because the have ⬇️ specific heat.
Melting state is easy.
Why amalgam is ⬆️ in thermal diffusivity?
⬆️ thermal conductivity
⬇️Density
⬇️specific heat
Why the large amalgam filling may cause pain to the patient? And what the solution?
Because of its ⬆️ thermal conductivity . The solution is dentin thickness should remain under the restoration or non-metallic cement base is placed between the tooth and filling for insulation.
How denture base can give tissue a healthy state?💪
If the denture base was metallic this give advantage in thermal conductivity wich leads to physiological response of VC,VD.
Why 100g of water 💧 is require more heat than 100g of alcohol?
The specific heat of the water ⬆️ than alcohol.
