Does freezing water require energy? It takes 100 calories to heat 1 g. water from 0˚, the freezing point of water, to 100˚ C, the boiling point. However, 540 calories of energy are required to convert that 1 g of water at 100˚ C to 1 g of water vapor at 100˚ C. Does the […]

What is the strongest intermolecular forces in alcohols? Alcohols contain the hydroxyl group (O—H) which produce intermolecular forces of attraction through hydrogen bonding. Hydrogen bonds are much stronger than Van Der Waals’ intermolecular forces. Why are alcohols stronger than alkanes? Hydrogen bonding In alkanes, the only intermolecular forces are van der Waals dispersion forces. Hydrogen […]

What is the relationship between inductance and current? This induced voltage created by the changing current has the effect of opposing the change in current. This is stated by Lenz’s law, and the voltage is called back EMF. Inductance is defined as the ratio of the induced voltage to the rate of change of current […]
