T/F If a mixture can be separated into pure substances via filtration, the original mixture was a solution. T/F If the melting point of gold is 1337 K, then a piece of gold at 1337°C would be in liquid form. T/F A volume measurement written as 0.392 L has uncertainty in the microlitre range. T/F Melting point is an intrinsic (or intensive) physical property. T/F Dissolving is a physical change.
