A room with an ambient temperature of 20\degree C20°C have TWO containers that are shiny metal and dull black. They were filled with warm water with the temperature of 65\degree C65°C .The container that would have the WARMEST water after TEN minutes is the (a) container
SELECT THE CORRECT ANSWERS TO BE FILLED IN THE BLANKS.
As shown in the diagram, take a plate with surface area A. With the thickness of __(a)__, Heat, Q is passing through the direction of __(b)__ axis. The rate of heat conduction per surface area is known as __(c)__ with the unit of \frac{W}{m^2}m2W
As the heat passed through the system at temperature T1, the temperature exiting the wall should be __(d)__ (higher/lower?) which is T2. Therefore, The rate of heat conduction through a plane layer is proportional to the __(e)__ across the layer and the __(f)__ but is inversely proportional to the __(g)__ of the layer.
(a) dx, (b) x, (c) heat flux, (d) higher, (e) temperature difference, (f) surface area, (g) thickness
(a) dx, (b) x, (c) heat flux, (d) lower, (e) temperature difference, (f) surface area, (g) thickness
(a) A, (b) x, (c) heat rate, (d) lower, (e) thickness, (f) surface area, (g) temperature difference
(a) dx, (b) y, (c) heat flux, (d) lower, (e) temperature difference, (f) surface area, (g) thermal conductivity
