Imagine two identical, sealed metal thermoflasks. Flask A is completely filled with hot water at 80 degrees C. Flask B is only half-filled with hot water at the exact same temperature of 80 degrees C. If both flasks are left in a cold room (0 degrees C) for two hours, Flask B's temperature drops significantly faster than Flask A's. Explain why.


What is Flask A has more mass, meaning it possesses a greater total amount of thermal energy to lose (or Flask B has less thermal capacity/mass to resist the temperature drop)?

The Walter Dale Bridge in Edmonton experiences various loads. If a massive line of heavy commercial trucks are idling bumper-to-bumper across the bridge deck, the top surface of the horizontal support beams directly under the tires undergoes this type of internal force, while the bottom surface of those same beams simultaneously undergoes this opposite internal force.
