A car travels at a speed of 41 meters/second using 756 joules of energy every second. Suppose we know that the car
uses 52,700 joules of energy. Set up a calculation to find the number of meters the car travels with this amount of energy.
Drag each tile to the correct location. The tiles can be used more than once.

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
