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 ...
A person at rest in the middle of a horizontal plane of perfectly smooth ice can bring themselves to the shore by using the first law of motion. This law states that an object at rest will remain at rest ...
The synchronizing satellite rotates around the Earth in a West to East direction. This rotation synchronizes with the Earth’s rotation, facilitating stable positioning relative to a point on the Earth’s surface. This alignment is essential for functions such as communication ...
The water level remains the same when the ice cube melts. This is because a floating object displaces an amount of water equal to its own weight. Since water expands when it freezes, the volume of the melted ice cube ...
Conservation of energy means that energy can neither be created nor destroyed. It can only change forms or be transferred from one object to another. This principle, based on the first law of thermodynamics, asserts that the total energy of ...
Automatic wrist watches get energy from the various movements of our hand. These watches contain a rotor that rotates with the movement of the wearer’s wrist. This movement winds the mainspring, storing energy that powers the watch’s movement and functions ...
