Document Summary

Under what certain pressure values and temperature condition is the condition of the substance in its most stable phase: triple point, le chatelia"s principle. Intensive properties do not scale with the system. The ratio of two extensive properties is an intensive property. #1. from the following list of variables/properties, circle any answers that are an. Heat is the flow of energy from one body to another. Heat flows from a hot object to a cold object. Heat does not flow from a cold object to a hot object. Work is the transfer of energy that doesn"t rely on a temperature difference. Mechanical work (moving of a piston, pulling an item) Electrical work (moving a charged body through a potential difference) W= f x d (p=force/area) f = p x a. Positive volume change = expansion = -ve work. Negative volume change = contraction = +ve work.
