Is the conductive heat flow rate the greatest, about the middle value, or the least amount of total heat flow through the window when both convection and conduction are important? Explain
What will be an ideal response?
Radiation is the predominant pathway for energy loss through windows. Both
conduction and convection play roles (see Extension 9.4), but these are less important to
heat loss than radiative losses through the windowpanes.

A 2.00-g bullet hits and becomes embedded in a 5.00-kg wood block which is hanging from a 1.20-m long string. This causes the block to swing through an arc of 3.50°. What was the speed of the bullet before it hit the block?
A) 16.7 m/s B) 524 m/s C) 25.3 m/s D) 262 m/s E) 789 m/s
A piece of iron of mass 0.12 kg is taken from an oven where its temperature is 336°C and quickly placed in an insulated copper can that contains 0.20 kg of water
The copper can has mass 0.50 kg, and it and the water in it are originally at a temperature of 20°C. Calculate the final temperature of the system, assuming no thermal energy is transferred to the surroundings. Use the following specific heats: 4190J/kg ? C° (water), 470 J/kg ? C° (iron), and 390 J/kg ? C° (copper).
