In a simple model of Earth's oceans, the upper layer of water that is well mixed by waves, wind, and heating by sunlight is about 500 m deep. This layer sit on a deeper layer of colder water beneath it. The area of the upper layer is about 3.60e+08 km² and its average temperature is currently about 17 °C. Suppose that the temperature of this upper layer is increased to 19.9 °C. (a) By how much will the volume of this layer increase? 1.12e14 ✓m³ (b) Assuming that the ocean does not significantly expand horizontally (so the area of this layer stays constant), by how much will sea level rise to accommodate the increase in volume of this layer as the temperature rises? 2.7 Xm (c) Express this sea level rise in inches: inches
An artist crafting a piece of metal in the forging studio plunges the hot metal into oil in order to harden it. The metal piece has a mass of 54 kg and its specific heat is 429.7 J/(kg K). The artist uses 810 kg of oil at 35°C, with a specific heat of 2999 J/(kg K), for the process. Once the metal is immersed in the oil, the temperature reaches an equilibrium value of 38°C. How hot was the forged metal piece just before it was plunged it into the oil? 276 X
