A piece of aluminum (bulk modulus 7.1 x 10¹0 N/m²) is placed in a vacuum chamber where the air pressure is 0.378 x 105 Pa. The vacuum pump is then turned on and the pressure is further reduced to zero. Determine the fractional change AV/V in the volume of the aluminum.

A block of wood floats in fresh water with 0.792 of its volume V submerged and in oil with 0.949 V submerged. Find the density of (a) the wood and (b) the oil. (a) Number i (b) Number i Units Units î

Consider the following experiment: 1.0 atm 1.0 mol N₂(g) 1.0 atm 3.0 mol H₂(g) ? The reaction chamber is initially divided by a partition into two unequal parts, as shown on the left side of the figure. The smaller volume contains 1.0 mol of N₂(g) at a pressure of 1.0 atm, while the larger volume contains 3.0 mol of H₂(g) at a pressure of 1.0 atm. The partition is removed, and the following reaction is carried out to completion in the combined volume shown on the right side of the figure: N₂(g) + 3 H₂(g) → 2 NH3(g). What quantities of which gases will be found in the reaction chamber after the completion of the reaction? (That is, what does the question mark on the right side of the figure stand for?) 0.5 mol N₂(g) 0.5 mol N₂(g) 0.0 mol N₂(g) 0.0 mol N₂(g) 0.0 mol N₂(g) 1.5 mol H₂(g) 1.5 mol H₂(g) 0.0 mol H₂(g) 0.0 mol H₂(g) 0.0 mol H₂(g) 2.0 mol NH3(g) 1.0 mol NH3(g) 2.0 mol NH3(g) 4.0 mol NH3(g) 1.0 mol NH3(g)

The gauge pressure in your car tires is 2.55 × 105 Pa at a temperature of 35.0°C when you drive it onto a ferry boat to Alaska. What is the gauge pressure of the tires, in pascals, later when the temperature has dropped to -40.0°C? Assume the volume of each tire does not change.
