What is relation between CP and CV?

What is relation between CP and CV? The specific heat of gas at constant volume in terms of degree of freedom ‘f’ is given as: Cv = (f/2) R. So, we can also say that, Cp/Cv = (1 + 2/f), where f is degree of freedom. Monoatomic gas has only one translational motion, hence three […]

What does 1 dB mean?

What does 1 dB mean? Decibel How does dB loss work? dB (decibel) Every time you double (or halve) the power level, you add (or subtract) 3 dB to the power level. This corresponds to a 50 percent gain or reduction. 10 dB loss corresponds to a tenfold decrease in signal level. A 20 dB […]

What is the formula of starch?

What is the formula of starch? The basic chemical formula of the starch molecule is (C6H10O5)n. Starch is a polysaccharide comprising glucose monomers joined in α 1,4 linkages. The simplest form of starch is the linear polymer amylose; amylopectin is the branched form. What is the structure and function of starch? Starch is the form […]

What is meant by Vsepr theory?

What is meant by Vsepr theory? The VSEPR theory assumes that each atom in a molecule will achieve a geometry that minimizes the repulsion between electrons in the valence shell of that atom. Repulsion between these pairs of electrons can be minimized by arranging them so that they point in opposite directions. Why is Vsepr […]

What are the mixtures that Cannot be separated? An element is a pure substance that cannot be separated into simpler substances by chemical or physical means. There are about 117 elements. What jobs use separation techniques? Familiar professions that use separation techniques Chefs – decanting, sieving, filtering. Dentists – safe disposal of mercury fillings (filtering). […]

What are climate change scientists called?

What are climate change scientists called? This effect, called global warming, is a particularly important object of study for climatologists. By studying global warming, climatologists can better understand and predict the long-term impact of human-caused climate change. Climatologists seek to understand three main aspects of climate. How many scientists are studying global warming? Nearly all […]
