Do we need oxidants? Oxidation can damage vital molecules in our cells, including DNA and proteins, which are responsible for many body processes. Molecules such as DNA are needed for cells to function properly, so if too many are damaged, the cell can malfunction or die. This is why antioxidants are important. Why are oxidants […]
What is the difference between IR and FTIR?
What is the difference between IR and FTIR? FTIR spectrometers have several prominent advantages: (1) The signal-to-noise ratio of spectrum is significantly higher than the previous generation infrared spectrometers. (2) The accuracy of wavenumber is high. Due to these advantages, FTIR Spectrometers have replaced dispersive IR spectrometers. What is the principle of IR spectroscopy? IR […]

Is radioactive decay bad?
Is radioactive decay bad? Radiation can either kill cells or damage the DNA within them, which damages their ability to reproduce and can eventually lead to cancer. When radiation is present, high energy particles pass through your body. These can collide with atoms in your body and disrupt atomic structure. What is a decay constant […]

What is another name for non-renewable resources?
What is another name for non-renewable resources? A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption.

Is forced hot air unhealthy?
Is forced hot air unhealthy? The biggest downside of using a forced air heating system is that it leaves you vulnerable to inefficiency stemming from ductwork problems. If your ductwork is well-designed, expertly installed, and kept in prime condition, then you’ll be able to heat your home quite efficiently. Is forced air heating cheaper? Other […]
What energies are involved in solution formation?
What energies are involved in solution formation? Energy is required for a solute to break its bonds. When you are forming a solution you need to break down the solute into its particles. The solute is the solid substance that you are dissolving. Bond breaking requires energy as the solute is relatively stable in its […]
