i need to design a tin that can hold 330ml of hot water It must keep the water hot for at least 1/2 hour and it must not cost more than $3 this is a school projectcan u make suggestions on what material to use and the steps for the design i appreciate ur help
Heat escapes by three ways: conduction, convection and radiationFor conduction, make sure the material is an insulator, such as styrofoamFor convection, just make sure the tin is airtightFor radiation, coat the tin with aluminium foil, either inside or outisde(or any other white and shiny material for that matter) That's all, simple and efficient eh?
