During his early years at the university, Newton realized that one can't just claim universal laws. What must the universal law be subject to?

Acid precipitation chemically weathering a 5.0-kg limestone rock . which coukd be the result ?

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.

What are two examples of phase changes that skip a phase during transition?
