7. a 5.0 g piece of metal is heated to 100°c, then placed in a beaker containing 20.0 g of water at 10°c.
the temperature of the water rises to 15°c. assuming that heat lost by the metal = heat gained by the
water. calculate the specific heat of the metal.

Strong conductivity of plasma allows it to act and react as and
