UV visible spectroscopy is a technique used to measure the absorption of ultraviolet and visible light by a substance.
UV visible spectroscopy involves passing UV and visible light through a sample and measuring the amount of light absorbed at different wavelengths.
It is commonly used in analytical chemistry to determine the concentration of a substance in a sample.
UV visible spectroscopy can also be used to study the e...
pH stands for potential of hydrogen and is a measure of acidity or alkalinity of a solution. It is a unitless scale ranging from 0 to 14.
pH measures the concentration of hydrogen ions in a solution, determining its acidity or alkalinity.
A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline.
Examples of pH levels: lemon juice (pH 2), water (pH 7), baking soda (pH 9).

Distillation is used in industries to purify liquids like alcohol, while eva...
I applied via Walk-in and was interviewed in Feb 2024. There was 1 interview round.
Cooling towers are used to remove heat from a building or industrial process by transferring it to the atmosphere.
Cooling towers can be classified into two main types: natural draft and mechanical draft.
Natural draft cooling towers use the stack effect to draw air through the tower, while mechanical draft cooling towers use fans to force air through the tower.
Examples of cooling tower types include crossflow, counterfl
Heat exchangers are devices used to transfer heat between two or more fluids.
There are several types of heat exchangers, including shell and tube, plate, and finned tube heat exchangers.
Shell and tube heat exchangers are commonly used in industrial applications, while plate heat exchangers are more compact and efficient.
Finned tube heat exchangers are often used in HVAC systems to increase heat transfer efficiency.
