This video breaks down the process of calculating the time and number of photons required to boil water in a microwave. Using given power, wavelength, and water specifics, we determine both energy needs and photon count.

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

Discover the intricacies of atomic radius and its trends on the periodic table in this video. Unravel the factors influencing atomic size and explore how elements' positions on the periodic table affect their atomic radii.

This video explores the process of fatty acid catabolism, highlighting its occurrence in the mitochondria, the crucial role of mitochondria in energy generation, and the metabolic reactions involved without revealing specific details or conclusions.
