An ideal gas can be considered as a collection of n weakly interacting particles each of point mass m confined to a cubic volume with linear dimensions l. using quantum mechanics write the energy levels of one such particle in terms of m, l and the quantum number of the state n. how does the number of accessible quantum states for a single particle vary with n? if each particle has on average the thermal energy 3/2 kbtwhat is the average value of the single particle quantum number at 273 k? considering that the density of an ideal gas at standard temperature and pressure 273 k and 1 atmosphere) is about 2.7 x 1019 atoms/cm3, what is approximately the number of different microscopic states that one cubic centimeter of such an ideal gas could (and will) have at 273 k andp-1 atmosphere? now increase t of the cubic centimeter of gas by 1 k. what is the change in the number of accessible microstates?

1. the materials manager for a billiard ball maker must periodically place orders for resin, one of the raw materials used in producing billiard balls. she knows that manufacturing uses resin at a rate of 50 kilograms each day, and that it costs $.04 per day to carry a kilogram of resin in inventory. she also knows that the order costs for resin are $100 per order, and that the lead time for delivery is four (4) days.2. at what point should resin be reordered? a. 0 kilograms remainingb. 50 kilograms remainingc. 200 kilograms remainingd. 400 kilograms remaininge. 500 kilograms remaining3. if order size was 1,000 kilograms of resin, what would be the length of an order cycle? a. 0.05 daysb. 4 daysc. 16 daysd. 20 dayse. 50 days4. if the order size was 1,000 kilograms of resin, what would be the average inventory level? a. 50 kilogramsb. 200 kilogramsc. 500 kilogramsd. 800 kilogramse. 1,000 kilograms5. if the order size was 1,000 kilograms of resin, what would be the daily total inventory costs, excluding the cost of the resin? a. $5b. $10c. $20d. $25e. $40
