A flask is filled with 1.53 L (L = liter) of a liquid at 94.8 °C. When the liquid is cooled to 18.2 °C, its volume is only 1.39 L, however. Neglect the contraction of the flask. What is the coefficient of volume expansion of the liquid?

A cylinder with a piston holds 0.50 m3 of oxygen at an absolute pressure of 4.0 atm. The piston is pulled outward, increasing the volume of the gas until the pressure drops to 1.0 atm. If the temperature stays constant, what new volume does the gas occupy? (a) 1.0 m3 (b) 1.5 m3 (c) 2.0 m3 (d) 0.12 m3 (e) 2.5 m3

Two cylinders A and B at the same temperature contain the same quantity of the same kind of gas. Cylinder A has three times the volume of cylinder B. What can you conclude about the pressures the gases exert? (a) We can conclude nothing about the pressures. (b) The pressure in A is three times the pressure in B. (c) The pressures must be equal. (d) The pressure in A must be one-third the pressure in B.

How many cubic meters of helium are required to lift a balloon with a 400-kg payload to a height of 8 000 m? Take He = 0.179 kg/m3. Assume the balloon maintains a constant volume and the density of air decreases with the altitude z according to the expression air = 0ez/8, where z is in meters and 0 = 1.20 kg/m3 is the density of air at sea level.

A liquid with a coefficient of volume expansion just fills a spherical shell of volume V(Fig. P19.51). The shell and the open capillary of area A projecting from the top of the sphere are made of a material with an average coefficient of linear expansion . The liquid is free to expand into the capillary. Assuming the temperature increases by T find the distance h the liquid rises in the capillary.

A cubic container of volume 2.00 L holds 0.500 mol of nitrogen gas at a temperature of 25.0 . What is the net force due to the nitrogen on one wall of the container? Compare that force to the sample's weight.

The pressure gauge on a cylinder of gas registers the gauge pressure, which is the difference between the interior pressure and the exterior pressure P0. Lets call the gauge pressure Pg. When the cylinder is full, the mass of the gas in it is mi at a gauge pressure of Pgi. Assuming the temperature of the cylinder remains constant, show that the mass of the gas remaining in the cylinder when the pressure reading is Pgf is given by mf=mi(Pgf+P0Pgi+P0)

Review. (a) Derive an expression for the buoyant force on a spherical balloon, submerged in water, as a function of the depth h below the surface, the volume Vi of the balloon at the surface, the pressure P0 at the surface, and the density w of the water. Assume the water temperature does not change with depth, (b) Does the bouyant force increase or decrease as the balloon is submerged? (c) At what depth is the buoyant force one-half the surface value?

Rectangular tank contains 3.0 kg of air. The length of the tank is 1.1 m and the width is 0.9 m. The pressure p of the tank is 1.2 bar temperature T₁ is -20 °C. Calculate a) Amount of air n b) Height of the tank h c) Density of air p mol (with zero decimal accuracy) m (with one decimal accuracy) kg/m3 (with one decimal accuracy) If the temperature inside the tank increases by 50 °C, what is the new pressure in the tank? d) New pressure P2 bar (with one decimal accuracy)

A flask is filled with 1.56 L (L= liter) of a liquid at 99.2 °C. When the liquid is cooled to 13.4 °C, its volume is only 1.38 L, however. Neglect the contraction of the flask. What is the coefficient of volume expansion of the liquid? Number Units
