SUMMARY
The discussion centers on a physics problem involving heating water by shaking a thermos flask. The physicist uses 380 cm3 of water at 58°F, shaking it 32 times per minute with each shake dropping the water 1.15 ft. To determine how long he must shake the flask to boil the water, participants suggest calculating the mass of the water, using the specific heat capacity of water (4.186 J/(g*K)), and finding the total energy required to reach the boiling point. The energy generated per shake is also a critical factor in solving this problem.
