What is magnetism? What are the basic forces? What causes a decrease in gravitational field? Why doesn't light carry momentum? Explain Electromagnetic Radiation. Explain what is a pseudo force? Include an example. What are the strength of intermolecular forces of methylated spirits acetone, water...
Spirits labelled 95 proof contain only about 47 per cent alcohol. Beware of methylated alcohol, which is very poisonous, and should never be added to drinking water. 20 If no other safe water supply can be obtained, tap water that is too hot to touch can be left to cool and is ...
If a minimal amount of shear force (maybe almost negligible) is applied on a matter, and this matter deforms continuously, then this matter is known as fluid. Usually, gases and liquids are called as fluid.Answer and Explanation: In the world, all the fluid changes its properties under the...
HPLC is usually reverse-phase, so the stationary phase is nonpolar. This makes the polar mobile phase and more polar substances being analyzed elute faster. Methanol is less polar than water, but more polar than organic solvents. Thus, using it in place of water will decrease elution time of...
What physical property of water makes it a great solvent for visible spectroscopy? Why Boiling point of water is more than hydrogen fluoride(HF)? What happens to the amount of oxygen present in soil when the soil becomes waterlogged? Why do methylated spirits evaporate faster than water? Why ...
