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...

BaseAcid or Base? Tastes bitter BaseAcid or Base? Feels slippery AcidAcid or Base? Blue litmus paper red An acid is a molecule that donates H^+ ions, so the molecule that lost a H^+ ion on the product side will be the acid. CH40 is the acid.Identify the acid in the following reaction: PH3 + CH40 → CH30- + PH4+
