The Kinetic Theory of Gases
... This result indicates that the pressure of a gas is proportional to (1) the number of molecules per unit volume and (2) the average translational kinetic energy of the molecules, 12m 0v 2 . In analyzing this simplified model of an ideal gas, we obtain an important result that relates the macroscopic ...

... The energy gained by the water is the Ematch = 4180 J.kg-1.K-1 m T. This is the energy supplied by the match. A bath tub contains around 300 l or 0.3 m3 which is around 300 kg of water. A nice hot bath is around 50oC, and tap water is typically at around 20oC, so you need a temperature change o ...
