The amount of heat gained (ΔQ) by a sample of water in a solar oven can be assumed to be the same for any substance in the same oven, provided that heat losses are neglected. This assumption holds true if the absorbing material's properties do not affect the heat transfer to the substances inside. However, variations in specific heat capacities and thermal conductivities among different materials can lead to differences in heat absorption rates. Therefore, while the assumption can simplify calculations, it may not accurately reflect real-world scenarios. Understanding these nuances is crucial for precise thermal analysis in solar cooking applications.
