density = mass / volume
if mass = 1 kg = constant =
density is inversely proportional to volume
d1 / d2 = V2 / V1
d1 / d2 = 0.5 / 1
d2 = d1 / 0.5
d2 = 2 d1............... doubles
One kg of air is compressed from 1m cube to 0.5m cube. What will be the...
At 400Celsius the following equilibrium quantities are found: [N2] = 1M, [H2] = 0.5M, [NH3] = 0.5M. How many moles of H2 must be removed from the container so that [N2] = 1.2M. What is the change in system pressure?
The pressure of compressed air is measured with a manometer filled with water. The density of water is 1000 kg/m3. If Patm = 84 kPa and the height of water in the manometer is 0.48 m, what is the gage pressure?
A cube of mass m1 = 5.1 kg is sitting on top of another cube of the same size and mass m2 = 1.4 kg while they are both in free-fall. Ignoring any air resistance, what is the magnitude of the normal force with which the bottom cube is acting on the top cube?
A cube with sides of length 1.50 cm is hung from a scale. The hanging cube is then immersed in water. If the scale reads 0.26 N, what is the density of the cube in kg/m3?
100 kg/hr of air is compressed from 110 kPa and 255 K (where it has an enthalpy of 489 kJ/kg) to 1000 kPa and 278 K (where it has an enthalpy of 509 kJ/kg). The exit velocity of the air from the compressor is 60 m/s. The inlet velocity is very small and can be neglected. The process is adiabatic and there is no change in height during the process. a) Label all known information on the diagram. State if...
A 5 kg solid cube has sides of length 8.6 cm. What is the density of the cube? answer in SI units of kg/m^3.
A ball of mass 0.083 kg is shot straight up in the air using a compressed spring. The spring has a spring constant of 328 N/m and is compressed by 0.05 m initially. The ball reaches a height of 0.252 m above the initial position. How much energy has dissipated due to frictional effects such as air drag ? (in J)
