WHAT IS DISTILLATION

distillation is a method to separate a mixture of the liquid with the help of difference in boiling point. the process involves evaporation and condensation

what is a fractional distillation

multiple simple distillations in one go are fractional distillation. used in cases where liquids have closer boiling points

applying the principle to our examples

2-butanone and t-butyl alcohol

2-butanone = boiling point = 79.64

t-butyl alcohol = boiling point = 82

very clear that boiling points are closer and we need to use fractional distillaion for separation

Diethylene glycol = boiling point = 244

huge difference = simple distillation can be used

a mixture of diethyl ether and chlorobenzene

diethyl ether = boiling point = 34.6

chlorobenzene = boiling point = 137

huge difference simple distillation worth of doing

Consider a simple series RLC circuit with the following values for the resistance, inductance, and capacitance: R = 110 Ω (ohms), L = 1 H (henries), and C = 0.001 F (farads). Furthermore, a battery provides an external voltage, e(t), into the circuit equal to 7 However, this external voltage e(t) is not always flowing into the circuit. Initially, the switch for the circuit is open and there is no charge or current flowing through the circuit. At time t...
