Deposition: Gas to Solid Without Becoming Liquid

Deposition is the direct transition of a substance from the gas phase to the solid phase, skipping the liquid state

Sublimation: Solid to Gas Without Becoming Liquid

Sublimation is the phase transition where a solid changes directly into a gas, bypassing the liquid phase entirely. How it

Superheating: When Liquids Exceed Boiling Without Vaporizing

Superheating happens when a liquid is heated above its normal boiling point but does not immediately boil or form vapor

Vapor Pressure: A Measure of Evaporation Tendency

Vapor pressure is the pressure exerted by a vapor when it is in dynamic equilibrium with its liquid (or solid)

Reynolds Transport Theorem: Bridging System and Control Volume

The Reynolds Transport Theorem (RTT) is a foundational concept in fluid mechanics that connects the system approach (following a fixed

Center of Pressure: Where Aerodynamic Forces Concentrate

The center of pressure is the specific point on a body—like a wing, rocket, or airfoil—where the total (net) pressure

Lift: The Force That Keeps Aircraft in the Air

Lift is the upward force that allows an aircraft to overcome gravity and stay in the air. It is generated

Drag Coefficient: Measuring Fluid Resistance

The drag coefficient is a dimensionless number that quantifies how much resistance (drag) an object experiences when moving through a

Efficiency: Measuring Energy Usefulness

Efficiency describes how effectively a system converts input energy into useful output energy. It is expressed as a ratio or

Power: The Rate at Which Work Is Done

Power is a measure of how quickly work is performed or energy is transferred. It tells us how fast something
