WebThe occurrence of BCC iron structure above 1394°C is due to large electronic specific heat of iron in general (on heating). The electronic specific heat of BCC iron is greater than FCC iron above about 300°C and becomes sufficiently greater at higher temperatures to make it stable again above 1394°C. 3. Effect of Pressure on Allotropy of Iron: WebWhen a system absorbs or loses heat, the average kinetic energy of the molecules will change. Thus, heat transfer results in a change in the system's temperature as long as the system is not undergoing a phase change. The change in temperature resulting from heat transferred to or from a system depends on how many molecules are in the system. incline ski and board shopWebA plateau A typical heating or cooling curve will have plateaus in the curve when there are constant temperatures. These constant temperatures occur when a substance is undergoing a phase transition.
