What is the intensity of UV light? The intensity of UV radiation is measured in the units of milliwatts per square centimeter (mW/cm2) which is energy per square centimeter received per second. Also, it is measured in the units of millijoules per square centimeter (mJ/cm2), which is energy received per unit area in a given […]
What causes sodium voltage-gated channels to open?
What causes sodium voltage-gated channels to open? When a stimulus reaches the threshold at the axon hillock, an action potential is generated. An action potential relies on many protein channels. All the voltage-gated Sodium channels open when the membrane potential reaches around -55 mV and there’s a large influx of Sodium, causing a sharp rise […]
What does the bubbling indicate?
What does the bubbling indicate? When substances are put in the same container like, CaCO3 and HCl . A reaction occurs and bubbles escape the container (effervescence). These bubbles are actually gas fumes, and this shows that a new gaseous product is formed. Here, bubbling indicates our chemical reaction. What are the bubbles that you […]
What cycle does a refrigerator work on?
What cycle does a refrigerator work on? Air cycle refrigeration works on Reversed Carnot cycle and Bell Coleman cycle. Air is compressed and then heat removed, this air is then expanded to a lower temperature than before it was compressed. . Where is refrigeration used? Refrigeration has many applications, including household refrigerators, industrial freezers, cryogenics, […]

What is the source of energy for the life in deep sea ocean trenches where sunlight does not reach?
What is the source of energy for the life in deep sea ocean trenches where sunlight does not reach? Answer: Instead of sunlight, vent life relies on hydrogen sulfide – more commonly known as rotten egg gas and toxic to most land-based life. In a process called chemosynthesis, specialized bacteria create energy from the hydrogen […]

Why metal is a conductor?
Why metal is a conductor? Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions. Are metals shiny? […]
