a cold metal object is put into a tank of hot water. based on the lumped capacitance model, if the convection heat transfer coefficient were decreased, the time it would take for the object to rise to a given temperature would

The convection heat transfer coefficient was decreased, and the time it would take for the object to rise to a given temperature would increase.The heats switch coefficient or movie coefficient, or movie effectiveness, in thermodynamics and in mechanics is the proportionality steady between the warmth flux and the thermodynamic driving pressure. the warmth switch coefficient is the heat transferred according to unit vicinity per kelvin. Heat transfer coefficient depends on both the thermal properties of a medium, the hydrodynamic traits of its float, and the hydrodynamic and thermal boundary situations.The convective heat transfer coefficient isn't a belonging of the fluid. it's by far an experimentally decided parameter whose cost depends on all the variables influencing convection, inclusive of the floor geometry, the character of fluid motion, the residences of the fluid, and the bulk fluid velocity.Learn more about heat transfer coefficient here:-https://brainly.com/question/15244352#SPJ4
