The temperature of an object is an indicator of the average kinetic energy of its molecules. It reflects the measure of the average energy associated with the random motion of molecules within the object. This kinetic energy determines the object’s ...

The unit of viscosity is Poise. Viscosity measures a fluid’s resistance to flow. It is defined as the ratio of shear stress to shear rate within a fluid. The Poise is the unit used to quantify viscosity, named after French ...
Ventilators are installed near the ceiling of the room because the exhaled hot air rises up and goes out. Hot air, being less dense, naturally ascends towards the ceiling. Placing ventilators there allows for the efficient removal of this hot ...
When detergent is added to pure water, the surface tension decreases. Detergent molecules disrupt the cohesive forces between water molecules at the surface, reducing the surface tension. This allows the detergent solution to spread more easily and penetrate surfaces, enhancing ...
Small pieces of camphor dance on the surface of water due to surface tension. When camphor is placed on water, it rapidly sublimes, releasing molecules into the air. As these molecules push against the surface tension of the water, they ...
