Presents the diagram of the problem, necessary formulas, clearance and numerical solution: On June 26, the US Brookhaven National Laboratory (BNL) announced that the Guinness World Records (GWR) organization had granted him the temperature record highest ever achieved: gold ion collisions at nearly the speed of light at the accelerator of Relativistic Heavy Ion Collider particles had formed a plasma at 4 billion degrees Celsius. Convert this value to ◦C and K.

Let's say you park your car outside overnight during the winter, when you first parked your car the temperature was 29.0 degrees C but overnight the temperature drops to -7.0 degrees C. If your initial gauge pressure was 200kPa, what will be the gauge pressure (in KPa) after the change in temperature?

This was wrong. Can you solve this again with these numbers? What is the root mean square velocity, vrms, for Hydrogen molecules (H2) at 20oC? Hint: How many amu does an H2 molecule contain. 1 amu = 1.67 x 10-27 kg Boltzman's Constant, k = 1.38 x 10-23 J/K Give your answer in m/s to 4 significant figures (NO DECIMALS)

Calculate the average density of the following astronomical body:  Jupiter. Where does the value fit among those listed in the table below? Look up the density of a typical rock, such as granite in another source and compare the density of Jupiter to it.

The vapor pressure of water at 25°C is 0.0313 atm. Calculate the vapor pressure in kPa.Round answer to 3 significant digits.

1.21 A team is designing a helium-filled balloon that will fly to an altitude of 80,000 ft. As the balloon ascends, the upward force (buoyant force) will need to exceed the total weight. Thus, weight is critical. Estimate the weight (in newtons) of the helium inside the balloon. The balloon is inflated at a site where the atmospheric pressure is 0.89 bar and the temperature is 22°C. When inflated prior to launch, the balloon is spherical (radius 1.3 m) and the inflation pressure equals the local atmospheric pressure.

Invalid path. A light balloon is filled with 383 m3 of helium at atmospheric pressure. (a) At 0°C, the balloon can lift a payload of what mass? kg (b) In the table below, observe that the density of hydrogen is nearly half the density of helium. What load can the balloon lift if filled with hydrogen? kg Densities of Some Common Substances at Standard Temperature (0°C) and Pressure (Atmospheric) p(kg/m3) p(kg/m3) Substance Substance Air 1.29 Ice 0.917 X 103 7.86 X 103 11.3 X 10 13.6 X 10 Aluminum 2.70 X 103 Iron Benzene 0.879 X 103 Lead 8.92 X 103 Mercury Copper Ethyl alcohol 0.806 X 105 Oak 0.710 X 103 Fresh water 1.00 X 103 Oxygen gas Pine 1.43 Glycerin 1.26 X 103 0.373 X 103 Gold 19.3 X 10 Platinum 21.4 X 10 1.03 X 10 10.5 X 10 Helium gas 1.79 X 10-1 Seawater Hydrogen gas 8.99 X 10-2 Silver
