In this instructional video, we explore the conversion of various pressure units into atmospheres, covering mmHg, bars, Torr, and kPa. The process involves utilizing conversion factors to ensure accurate results for each unit. By the end, you'll have equivalent pressures in atmospheres for the given values, enhancing your understanding of pressure conversions.
Lattice Energy: Always Positive; Hydration Energy: Always Negative

In this video we clarify why lattice energy in solids is always a positive value due to the energy needed to separate ions making it an endothermic process. On the flip side hydration energy is always negative as it releases heat when ions dissolve in water making it an exothermic reaction. We use sodium chloride as a real-world example to illustrate these crucial thermodynamic concepts
