Briefly answer the following:
(a) If someone says that temperature is howhot or cold it feels, would you agree?
(b) If heat energy is transferred from room A toroom B, can you automatically conclude that A must have a highertemperature than B?
(c) Why canât you buy a thermostat with wateras a working substance?
(d) Two gases are at the same temperature andpressure. Do they have the same internal energy and particle speed?(Be careful what you assume.)
(e) On a cold day you could rub your hands togetherto warm them up a bit. What is transferred to the hands, heat orwork?
(f) Why is it necessary todistinguish heat capacity for constant volume or constantpressure?
(g) When a gas expands isothermally underconstant pressure, how does the enthalpy change?
(h) If the speed of gas particles decreases, howdoes the mean free path change? Mean collision time?
(i) If the gas particle density isdoubled, how does it affect thermal conductivity?
