3.5 kilograms of water in a container have a pressure of 100 kPa and temperature of 150oC. What is the volume of this container?

Density is how much you have in a volume. If I put 14.76 kilogram(s) of carbon dioxide in an empty 2.11 m3 bottle, what is the density of the gas after filling it? Round to nearest 2 decimals.

The figure shows particles 1 and 2, each of mass m, attached to the ends of a rigid massless rod of length L₁ + L₂. with L₁ -0.79 m and L2 -3.3 m. The rod is held horizontally on the fulcrum and then released. What are the magnitudes of the initial accelerations of (a) particle 1 and (b) particle 2? (a) Number (b) Number i Units Units 14 -Lg-

In a hypothetical diesel engine the fuel is compressed from 528mL to 39.7 mL.  This rasies the temperature of the fuel form 25°C to its ignition temperature of 210°C.  If the fuel begins at 1.00atm, what is the pressure of the fuel at its ignition temperature.? Express your answer to 1 decimal place.  Be sure to use the proper abbreviation of the UNITS

A cylinder containing 239.6 cubic centimeter of gas at a pressure of 342 kPa when its temperature is 406 K. Given that its volume is unchanged when the pressure was increased by a factor of 1.2, Determine the new Temperature of the gas (In Kelvin). Note: Your answer must be in Kelvin, however, do not include the unit, just enter the magnitude that corresponds to the final volume in Kelvin. Round your answer to 2 decimal points Round your answer to 2 decimal points

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)

Still think that unit conversion isn't important? Here is a widely publicized, true story about how failing to convert units resulted in a huge loss. In 1998, the Mars Climate Orbiter probe crashed into the surface of Mars, instead of entering orbit. The resulting inguiry revealed that NASA navigators had been making minor course corrections in SI units, whereas the software written by the probe's makers implicitly used British units. In the United States, most scientists use Sl units, whereas most engineers use the British, or Imperial, system of units. (Interestingly, British units are not used in Britain.) For these two groups to be able to communicate to one another, unit conversions are necessary. The unit of force in the SI system is the newton (N), which is defined in terms of basic Sl units as 1 N=1 kg · m/s?. The unit of force in the British system is the pound (lb), which is defined in terms of the slug (British unit of mass), foot (ft), and second (s) as 1 lb =1 slug ·…

q20 Lead metal has a high density of 11,300 kg/m3. What is the mass of 535 cm3 of lead metal? Enter the numerical part of your answer (in kg) to 3 significant figures.

A large tank is filled to capacity with 500 gallons of pure water. Brine containing 2 pounds of salt per gallon is pumped into the tank at a rate of 5 gal/min. The well-mixed solution is pumped out at the same rate. a) Find the number A(t) of pounds of salt in the tank at time t. b) what is the concentration c(t) of the salt in the tank at time t? At t=5 min? What is the concentration of the salt in the tank after a long time (we can this concentration the limiting value), that is, as t→--? At what time is the concentration of the salt in the tank equal to one-half this limiting value? 500 gallons
