WebMar 1, 2024 · To understand the work of the vacuum flask it is important to know the basics of three ways how heat moves. Heat is an energy that can move whis help: Convection; Conduction; Radiation. Convection is the process when heat rises upwards. Its density is lower than one of cold air, so it moves up and cooler air gets out of its way. WebJan 5, 2024 · This is due to a phenomenon called heat transfer, which is the flow of energy in the form of heat.
