An engineer works in an automobile company where engines are designed. You are asked to design brass-based pistons that will slide into steel cylinders. The engine in which the pistons will be used will operate between 20 ° C and 150 ° C C. Calculate the percent change in the volume of the piston. Use: abrass = 2.0 x 10-5 (°C) -1 asteel= 1.2 x 105(°C) 1 atitanium = 8.5 × 10-6(°C) -1

An airtight dispenser for drinking water is 25 cm × 10 cm in horizontal dimensions and 20 cm tall. It has a tap of negligible volume that opens at the level of the bottom of the dispenser. Initially, it contains Water to a level 3.0 cm from the top and air at the ambient pressure, 1.00 atm, from there to the top. When the tap is opened, water will flow out until the gauge pressure at the bottom of dispenser, and thus at the opening of the tap, is 0. What volume of water flows out? Assume the temperature is constant, the dispenser is perfectly rigid, and the water has a constant density of 1000 kg/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.
