1. Kelvin - a temperature scale that begins at absolute zero, where there is no molecular movement (Water freezes at 273 K and boils at 373 K.)
2. Prototype - an original type that serves as a model for later example.
3. Convection - the transportation of heat from one place to another by the movement of a liquid or gas (A classroom is warmed by a hot air blower due to convection.)
4. Conduction - the transportation of heat or electricity from one place to another directly through an object (A frying pan is warmed by a hot stove due to conduction.
5. Median - the middle number in a set of ordered data (The median of {1,1,1,2,4,6,6} is 2 since 2 is the middle number when all of the numbers are placed in order. If there are an even number of numbers, the median is the mean of the two middle numbers.)
