... There are two situations in which the cumulative effects of unbalanced forces acting on a particle are of interest to us. These involve: a) forces acting along the trajectory. In this case, integration of the forces with respect to the displacement leads to the principle of work and energy. b) forces ...

... Process 2: This will be a two-stage process: (i) Decrease (instantaneously) the cylinder pressure to 2.5 atm; then the volume will be 4 l, since this is similar to Process 1. (ii) Then further decrease the pressure (instantaneously) to 1 atm with a volume of 10 l. The work is the sum of these two pr ...

Enthalpy
... The molecules in a solid are vibrating in place. Temperature is a measure of the average kinetic energy that the molecules. As the temperature rises, more kinetic energy is added and the molecules vibrate more. At one particular temperature, the molecules begin to tumble past each other. This breaki ...

... The heat an object contains is the amount of its thermal energy, measured in joules or J. Let's look at two examples to see the difference between temperature and heat. A swimming pool at 30°C is at a lower temperature than a cup of tea at 80°C. But, the swimming pool contains more water, so it stor ...
