1.What is the temperature of a 3.25 mm cube (e=0.273) that radiates 56.4 W?

2.Water (c=4.184 J/g°C) flows through an engine that produces 43.9 W of waste heat. If the water temperature increases by 21.8°C, what is the mass flow rate (m/t)?

3.A 3.78 mm copper cube (k = 392 W/m·°C) has a temperature difference of 11.4°C between opposite sides. How quickly does it conduct?
