Three identical 10 l tanks contain 6 mol of helium (he) at 293 k. the pressure in each of the tanks is increased as described below: tank a: the tank volume is decreased from 10 l to 5 l while the temperature and the number of moles of he remain constant. tank b: the tank temperature is increased from 293 k to 308 k while the volume and the number of moles of he remain constant. tank c: the number of moles of he in the tank is increased from 6 mol to 9 mol while the temperature and the volume remain constant. how is the average kinetic energy, ke, of the he molecules affected in each case?

Liquid from a brewery fermentation contains 10% ethanol and 90% water. part of the fermentation product (50,000 kg/h) is pumped to a distillation column on the factory site. under current operating conditions, a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate of one-tenth that of the feed. what is the composition of the waste "bottoms" from the still?
