Density is the mass of a substance per unit volume, measuring how tightly packed matter is within a material. It determines if an object sinks or floats, with higher-density materials like metals feeling "heavier" and lower-density materials like wood or gas feeling "lighter".

Steady State Two Dimensional Convection Diffusion Equation
In this video, we visualize the classic 2D convection-diffusion problem. We break down how temperature distribution depends on the kinematic velocity field and two crucial physical parameters: the Reynolds (Re) and Prandtl (Pr) numbers.

What looks like delayed motion is actually a property of the material itself. When a substance is thick, it resists flow more strongly, causing movement to slow down significantly. This resistance to flow is known as Viscosity.
Thicker materials (high viscosity) move slowly because their internal particles experience greater friction, while thinner ones flow quickly. Temperature and composition can also change how easily something moves.

Did you know that water absorbs more heat to evaporate than it does to boil?
Check out this quick breakdown of Enthalpy of Vaporisation!
From boiling at 100°C to evaporation at 25°C, we're simplifying the science behind how water transforms!
Here are some key takeaways:
Boiling (100°C): ΔH = +40.7 kJ/mol
Evaporation (25°C): ΔH = +44.7 kJ/mol
Fusion: ΔH = 6 kJ/mol
Understanding these concepts is crucial for mastering thermodynamics!

This Liquid Is So Thick… It Forgets How to Fall 🧪
Some liquids flow so slowly that gravity seems almost powerless against them. High-viscosity fluids—like pitch or certain polymers—resist motion because their internal molecular friction is extremely strong. Instead of pouring smoothly, they stretch, creep, and barely drip over time.
A famous demonstration is the Pitch Drop Experiment, where pitch appears solid but forms a single drop only once every several years. It’s not frozen—it’s just moving unbelievably slowly.
When viscosity dominates gravity, flow becomes patience.
Not solid.
Just incredibly slow.
