Convert Degrees Celsius to Kelvin - T(K)= T(C) + 273.15 Absolute Zero for Celsius and Kelvin - -273.15 C 0 K The unit size of the Celsius and Kelvin scale is the same. Boiling Point (C) and Kelvin and Freezing point - Boiling: 100 deg. C and 373.15 K Freezing: 0 deg. C and 273.15 K Extensive properties - Depends on the amount of the same Ex: mass and volume (these are physical properties) intensive properties - independent of the amount of the sample -Only intensive propert...

For immature teeth, primary teeth and metal crowns which test- cold, ept, heat, percussion - cold test Child primary mo do caries t/t - 1-mod amalgam,2- MO DO amalgam,3- mo do composite - MO DO amalgam Composite compare to gic has better - good translucency, better wear - better wear . Composite indirect casting has advantage on direct composite - less polymerization, more polymers - less polymerization shrinkage in the case of indirect composite casting.Superior esthetics, higher a...

If you change your name or address, how many days do you have to inform the board? - Answer- 10 days tooth info (misc) - Answer- *teeth composed of calcium, phosphorus, and other minerals *Teeth and bones are both hard, white and heavy with calcium, but that doesn't make them one and the same * hardest part of the human body , teeth mostly consist of a calcified tissue called dentine *dentin and cellular cementum can heal itself/grow new tissue *enamel can NOT regrow or heal itself di...
