How are temperature and kinetic energy related?
(Blackmail Question: If calling team answers correctly then they get to deduct a total of 200 points from other teams)
All molecules move or have kinetic energy. As the molecules move faster they create more heat, increase in temperature. As molecules slow down they decrease in temperature.

What is the difference between a homogeneous mixture and heterogeneous mixture? Give an example for each.
Homogeneous mixtures the particles are dissolved and not easy to distinguish, where as, heterogeneous mixtures need stirring or mixing to combine particles and particles are easy to distinguish.
