Consider a copper plate that has dimensions of 3 cm x 3 cm x 7 cm (length, width, and thickness, respectively). As shown in the following figure, the copper plate is exposed to a thermal energy source that puts out 126 J every second. The density of copper is 8,900 kg/m³. Assume there is no heat loss to the surrounding block. 126 J Copper Insulation What is the specific heat of copper (in J/(kg. K))? J/(kg K) What is the mass of the copper plate (in kg)? kg How much energy (in J) will be consumed during 11 seconds? K Determine the temperature rise (in K) in the plate after 11 seconds.

Expert Solution
Step 1
Given data
Dimension of plate = 3cm × 3cm × 7cm
Density of copper = 8900 kg/sec
Energy per second = 126 J
What is the specific heat of copper
Find the mass of copper and energy during 11 seconds also find temperature rise after 11 seconds.
