A copper plate, with dimensions of 3 cm x 3 cm x 5 cm (length, width, and thickness, respectively), is exposed to a thermal energy source that puts out 150 J every second, as shown in the accompanying figure. The density of copper is 8900 kg/m3 . Assuming no heat loss to the surrounding block, determine the temperature rise in the plate after 10 seconds.
