... Pay attention that if P=const and A is the work of expansion then dQ and dA=PdV are exact differentials. Let's consider heat exchange, one introduces the quantity of heat ∆Q in the system (∆V=0): ∆Q=∆U. Now let's suppose ∆V>0. Let's find out, is it necessary to write ∆Q=∆U-P∆V or ∆Q=∆U+P∆V. It is ne ...

... Mixtures are a physical blend of at least two substances; have variable composition. They can be either: 1) Heterogeneous – the mixture is not uniform in composition • Chocolate chip cookie, gravel, soil. 2) Homogeneous - same composition throughout; called “solutions” • Kool-aid, air, salt water ...
