The Icelandic waterfall, Glymur, is 198 metres high. Imagine a world where all the gravitational potential energy of the water at the top of the falls was converted to thermal energy at the bottom of the falls. What would be the temperature increase of the water at the bottom? Hint: consider one kilogram of water going over the waterfal.

Q4: A 50.0-g copper calorimeter contains 250 g of water at 20.0°C. How much steam at 100°C must be condensed into the water if the final temperature of the system is to reach 50.0°C? Note: Water Latent Heat of Vaporization (J/kg) =2.26 x 10°. Copper Specific Heat (J/kg. °C) = 387. Water Specific Heat (J/kg. °C)=4 186.
8. Consider a cubical building with sides of length 7 m. The walls are made of concrete with a thickness of 0.25 m and thermal conductivity of 0.8 W/m · °C. The temperature outside is Tout = -5 °C, while the temperature inside is Tin = 20 °C. How much energy (in joules) must the heating system provide in 12 hours to maintain the inside temperature constant? Assume heat cannot escape through the floor. In other words, assume that heat escapes through only five sides of the cube. Show your work.

The four identical gaps between the sections are provided so that thermal expansion will not create the thermal stress that could lead to cracks. What is the minimum gap width necessary to account for an increase in temperature of 40 °C?
