- A balloon is inflated to 2.50 L with nitrous oxide gas, N20, at a particular initial temperature and pressure, and tied-off. To what volume will the balloon contract or expand when:There are two important isotopes of uranium, 235 U and 238 U ; these isotopes are nearly identical chemically but have different atomic masses. Only 235 U is very useful in nuclear reactors. Separating the isotopes is called uranium enrichment (and is often in the news as of this writing, because of concerns that some countries are enriching uranium with the goal of making nuclear weapons.) One of the techniques for enrichment, gas diffusion, is based on the different molecular speeds of uranium hexafluoride gas, UF6 . (a) The molar masses of 235 U and 238 UF6 are 349.0 g/mol and 352.0 g/mol, respectively. What is the ratio of their typical speeds vrms ? (b) At what temperature would their typical speeds differ by1.00 m/s? (c) Do your answers in this problem imply that this technique may be difficult?Two molecules are diffusing in a water solution held at the sametemperature T. Molecule A has three times the mass of molecule B. Molecule A also has a mean free path that is half that of molecule B. Both need to diffuse over the same distance (Xeff). How do the diffusion speeds compare? (Express your answer in terms of a “A over B” ratio)
- Determine the carburizing time (in s) necessary to achieve a carbon concentration of 0.44 wt% at a position 1.7 mm into an iron- carbon alloy that initially contains 0.031 wt% C. The surface concentration is to be maintained at 1.2 wt% C, and the treatment is to be conducted at 1250°C. Assume that Do = 5.1 x 10-5 m²/s and Qd = 154 kJ/mol. You will find the table below useful.

Fuel economy drops as speeds increase from 55 to 65 mph, then decreases further as speeds increase to 75 mph. Explain why this is the case.(a) If you toss 10 coins, what percent of the time will you get the three most likely macrostates (6 heads and 4 tails, 5 heads and 5 tails, 4 heads and 6 tails)? (b) You can realistically toss 10 coins and count the number of heads andtails about twice a minute. At that rate, how long will it take on average to get either 10 heads and 0 tails or 0 heads and 10 tails?
- A sample of 2.37 moles of an ideal diatomic gas experiences a temperature increase of 65.2 K at constant volume. Find the increase in internal energy if only translational and rotational motions are possible.A 75 W light bulb is used for 12 hours a day. The electricity for this bulb comes from a natural gas fired power plant that operates with 49% efficiency. How much CO₂ is emitted per day to power this light bulb? Make a simple estimate of the CO2 emissions from the power plant, ignoring transmission losses. 0.0024 kg CO2/day Xx 0.0024 We mentioned earlier in the course that energy technologies in developing countries often have much lower efficacies than those in developed countries. Let's look at one example, lighting via kerosene lamps, which are common in developing countries but about 150x less effective than incandescent lightbulbs at turning energy into useful light. If a family wanted just one tenth of the light provided by the 75 W lightbulb, they'd need to consume 15x as much power, or 1125 W. If a family ran 1125 W worth of kerosene lamps for just 2 hours each day, how much CO2 would this emit? You may assume that kerosene produces the same emissions as gasoline. 3.00 kg…True/False The particle transport loss due to diffusion in a circular tube is dependent on tube diameter and particle diffusivity.
- A cell doesn’t need a circulatory system, but your body does. Let’s do a quick calculation to see why. A typical cell has a diameter of 10 mm. The smallest mammals in the world, shrews, are about 10 μm across.
