Gold has a very low specific heat value (.13 j/gºc) and is often used as a
conductor in airbags and smoke alarms. based on the relationship between
specific heat and conductivity, explain why gold is a good choice for these
applications.

An air-standard stirling cycle operates with a maximum pressure of 600 psia and a minimum pressure of 10 psia. the maximum volume of the air is 10 times the minimum volume. the temperature during the heat rejection process is 100°f. calculate the specific heat added to and rejected by this cycle, as well as the net specific work produced by the cycle. use constant specific heats at room temperature. the properties of air at room temperature are r
