Fused quartz possesses an exceptionally low coefficient of linear expansion, 5.50 × 10-7 (c°)–1. imagine you had a bar of fused quartz of length 3.49 m at 20.0°c. by how much, in millimeters, would the bar expand if you heated it to 213°c?

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
