Document Summary
Reading: from chapter 7 of petrucci et al. sections. Thermodynamics studies the bulk properties of matter and deduces a few general laws. It does not require any knowledge/ assumptions of molecules. A system where energy and matter can be exchanged with the surroundings. A system where energy but not matter can be exchanged with the surroundings. A system where neither energy nor matter can be exchanged with the surroundings. In thermodynamics we are interested in the flow of energy, typically in the forms of heat and work. Heat and work occur when there is a process. In the case of a material that does not change phase, the increase in temperature of a system. T due to the input of a given amount of heat q is given by. The heat capacity is a constant that depends on the system. It is better to be able to define heat capacity in terms of a particular compound:
