Q1: How many degrees of freedom are there in a gas of N molecules of helium? Recall that a helium molecule is monatomic (one atom per molecule). Q2: Noting that a hydrogen gas molecule (diatomic $H_2$) will not vibrate at room temperature, $T = 300 K$, how many degrees of freedom does the hydrogen gas molecule have at room temperature? Q3: A bottle of volume $V = 0.40 m^3$ contains hydrogen gas (a diatomic gas) at a pressure $p = 523,164 Pa$ (Pascal = $N/m^2$) and temperature $T = 310 K$. Recall that hydrogen molecules cannot vibrate at room temperature. Calculate a numerical value for the internal energy $U$ of this gas. Q4: The hydrogen molecule will start to vibrate at temperatures above roughly 1000 K. At this high temperature, what is the ratio of the internal energy of hydrogen gas to the internal energy of helium gas, assuming that the number of molecules in each gas is the same.

Rossiter Fittings produces two models of pipe fittings for underwater lines. The two models (RF-12 and RF-25) have the following characteristics, as developed by a product cost analyst: Selling price per unit Variable cost per unit Expected units sold per year RF-12 $ 427 RF-25 $ 567 $ 347 $ 407 3,627 12,493 The total fixed costs per year for the company are $1,164,400. Required: a. What is the anticipated level of profits for the expected sales volumes? b. Assuming that the product mix is the same at the break-even point, compute the break-even point in units. c. The head of marketing agrees with the data provided by the cost analyst but believes that the sales of the RF-12 model will be double in units from what the cost analyst predicts. The head of marketing agrees that the total unit volume is likely to be as predicted by the cost analyst. What would be the break-even point of sales in units using the assumptions of the head of marketing?
