If a puddle of liquid on a table is converted into a collection of 28 drops, by what factor c =
does the surface energy change? Round your answer to two decimals. Assume that the original pool
was flat with a depth of 1.2 mm and that the drops are spherical caps (you can Google this), each with
a height of 4.0 mm and a radius of 10.5 mm. The side area of the puddle can be neglected.

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?

this cylinder has a rod inside (same height as the cylinder), around the rod there is paraffin wax that will expand, I want to know how to reduce the thickness of this cylinder. However, I don't know what formulas I need to be able to do this. Can you explain the process I have to do? Please can you make an example with the data you choose to have an example of how to do this step by step? Thank you Also keep in mind that the wax is expanding by an induction coil, and the heat is happening around the cylinder. And the thickness of the stainless steel cylinder has to be thin but not so thin that it causes a pressure problem. So is more of a geometry problem. Thank you
Need help, please. Suppose you have 8.4 L of an ideal gas at 25 °C initially in a container equipped with a piston. You arrange to keep the pressure on the gas equal to 2 atm as you compress the gas to a volume of 2 L. How much work does it take to compress the gas?

Constants One way to improve insulation in windows is to fill a sealed space between two glass panes with a gas that has a lower thermal conductivity than that of air. The thermal conductivity k of a gas depends on its molar heat capacity Cy , molar mass M, and molecular radius r. The dependence on those quantities at a given temperature is approximated by k o Cv/r2 VM. The noble gases have properties that make them particularly good choices as insulating gases. Noble gases range from helium (molar mass 4.0 g/mol, molecular radius 0.13 nm) to xenon (molar mass 131 g/mol, molecular radius 0.22 nm). (The noble gas radon is heavier than xenon, but radon is radioactive and so is not suitable for this purpose.) Part A What is one reason the noble gases are preferable to air (which is mostly nitrogen and oxygen) as an insulating material? Noble gases are monatomic, so no rotational modes contribute to their molar heat capacity. noble gases are monatomic, so they have lower molecular masses…
