Several common systems have a "two state" nature. Coins land with either Heads or Tails, electronic spins have magnetic moments m pointing either (Up) or (Down). The terms "microstate" and "macrostate" describe these systems, each containing a number of objects or steps:

The experiments with static charges were done by:

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?

A0.750 kg aluminum pan is removed from the stove and plunged into a sink filled with 10.0 kg of water at 293 k. the water temperature quickly rises to 297 k. what was the initial temperature of the aluminum pan? the specific heat of aluminum is ca = 900 j/(kgk) and water is cw = 4190 j/(kgk)
