Why conduction does not take place in liquid? It is because of property of fluids (liquid and gases) that molecules are loosely packed and physically move around in the medium to transfer energy (heat) this is convection wherein solids molecules are tightly packed and they can only vibrate at a their place and can’t move […]

Does rising air warm or cool?
Does rising air warm or cool? Rising air always cools, and, conversely, sinking air always warms. This type of temperature change, which is caused simply by ascent or descent in the atmosphere, is called adiabatic cooling or warming. When air moves vertically, its pressure changes. What causes the air mass to cool what happens to […]
Is gold monatomic or diatomic?
Is gold monatomic or diatomic? Some sources cite the different color of the gold from its usual yellow color as evidence of it being monatomic. Any chemist (or alchemist, for that matter) knows gold is a transition metal that forms colored complexes and also assumes different colors as a pure metal as a thin film. […]
How does electric motor works and what is its importance?
How does electric motor works and what is its importance? Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft. General-purpose motors with standard dimensions and characteristics provide convenient mechanical power for industrial […]
