- Basing from the results (attached pic) describe briefly the effect of varying the box length (or volume) on the number of particle collisions on the wall and pressure exerted by the gasAt a certain location the surface temperature is 34⁰C and the lapse rate is -8.7⁰C/1,000 m. A parcel of air with a temperature of 28⁰C has been lifted to an altitude of 950 m. Is the parcel of air stable or unstable?A sample of H2 gas is collected over water at 21.5 degrees C and atmospheric pressure is 765 torr. The height of liquid in the eudiometer is 13.0 cm. What is the partial pressure of the H2 gas? Make sure to convert cm to mm and use density ratio. Use equation: PH2 = Pbarometric - PH2O - Pliquid column
- The ideal gas law has many applications in science, which includes calculating the concentration density, and molecular mass of a gas. Assume you have a gas cylinder nitrous oxide. The cylinder volume is 50 liters. What is the density of the gas in units of grams per liter at STP (standard temperature and pressure)? Show all work for full credit1) Calculate the experimental "R" using the data above: 2) Calculate the experimental Molar Volume.The following is the van Deemter Equation. Explain briefly the parameters A, B and C and how they affect the hight of the theoretical plate (H).
- Compute the volume percent of graphite VGr in a 3.8 wt% C cast iron, assuming that all the carbon exists as the graphite phase. Assume densities of 7.9 and 2.3 g/cm3 for ferrite and graphite, respectively. Answer in Vol%Let's say you are interested in measuring the radiocarbon content of atmospheric CO2 in a relatively clean location. How large of an air sample (in liters) would you need to take to get a sample of 1 mg of carbon? Assume a mixing ratio of CO2 in of 415 ppm and that you are sampling under standard conditions of temperature and pressure (1 mol = 22.4 l).The pressure exerted on the gas entrapped in the syringe is proportional to the total mass on the platform. Make two plots. (i) Vol/mL vs. Total mass/g (ii) Vol/mL vs. 1/(total mass/g) If warranted, obtain a trendline and trendline equation. Comments in the results. Is Boyles Law obeyed? Explain.
- The gas left in a used aerosol can is at a pressure of 199.5 kPa at 292.9K. If the can is thrown into a fire what will the internal pressure of the gas be when its temperature reaches 1,015.1K? Answer in units of kPa. Round your result to the nearest tenth. Please include all steps, formula used, and a clear handwriting. Thank you!A handgun was accidentally dropped on a hard fioor and fired. If the butlet weighs 40.9 g and the: handgun weighs 2.6Kg. what is the velocity of the buliet is the handgun recolled at 6.15m/s?Hello, Thank you for this response. This is the formula I used to find this, but my professor said that it was the incorrect formula. That I had found rms velocity, rather than velocity distribution.. I am not sure which formula I am supposed to use.
