Kinetic energy is energy of motion. The kinetic energy of an object is dependent on two variables, speed and mass and can be represented by the formula
KE - 1/2mv?
1) Four balls were rolled at a set of wooden pins. The balls were rolled with different amounts of force so that they traveled at approximately the same speed. Will there be a difference in the amount of
pins knocked down? Explain

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
