The purpose of experiment is to review the physical concepts and relationships associated with the flow of heat in and out of materials by determining the specific heat of the specific materials in the temperature range between boiling water and room temperature water. by doing so, we will come to a deeper understanding of the principle of conservation of energy as it applies to thermal equilibrium principle.

As the distance from a magnet increases, what happens to the magnet force?

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)
