n section 1.2 one reads “The composition of the gas sendout will consist of natural gas, liquefied natural gas, propane-air gas, and synthetic gas in varying proportions depending upon the gas supply situation at any given time. The normal range of heating value will be from 1000 to 1200 Btu per cubic foot (cu. ft.) of gas”. Use standard enthalpies. Assume that gas supplied by BGE is methane. Calculate heating value.

A typical bathroom sink faucet releases about two gallons of water every minute. a) If it takes you 2.5 minutes to brush your teeth and you leave the water run for the entire time, how much water would be used? b) If you only run the water for 30 seconds, how much water would be used?
Gauge pressure is the pressure read by a pressure gauge. The gauge pressure will be zero if the pressure is the same as the general atmospheric pressure, because the gauge measures only the excess above atmospheric pressure. The actual pressure will thus be atmospheric pressure plus gauge pressure. Atmospheric pressure is about 14 pounds per square inch. The Rankine temperature scale is the Fahrenheit verson of the absolute temperature, and absolute zero in Rankine is about -460 F. Now, imagine a football has been stored in a warm locker room at a temperature of 71 F, and has a gauge pressure of 12.5 pounds per square inch. Next, it is taken outside and cooled to 40 F. What will the gauge pressure be after this is done?
For this problem, we want to estimate the answer, so our assumptions may be a little unrealistic. Suppose we want to estimate how much air we need to send to a space station, assuming we cannot recycle air. Suppose four astronauts are in a spherical space station. If each of them typically breathes about 500 cm³of air with each breathe, and take 15 breathes per minute (average resting value): a. What is the volume of air you would need in the space station if these four astronauts stayed for a full year? b. If the density of air is 1.25 kg/m³ and it costs (thanks to SpaceX) a mere $100/kg to send objects to the space station, how much money would the astronaut air supply cost?

The density of platinum is 21.45 x 103 kg/m3. a. Calculate the volume (in m3/atom) occupied per platinum atom b. Estimate the atomic diameter (in m);(The estimate uses the approximation that it is a cubic volume) c. Using this estimation, calculate the thickness of a metal foil (in m) containing 2.0 x 101 atomic layers of platinum.
