Due to the high specific heat and low conductivity of water, only the uppermost 10% of the oceans is able to undergo any significant temperature change.
a. The natural variation in ocean levels is about 10 cm from September to March. By how much does the mean temperature of the upper ocean change during this time?
b. Global warming is likely to cause a rise in sea level for a number of reasons, one of which is the thermal expansion of water. Determine the rise in sea level for every 1.0 C° temperature increase in the upper ocean.
Data for the oceans
measurement value
surface area 3.61 × 1014 m2
mean depth 3794 m
mean temperature, overall 3.5 °C
mean temperature, top 10% 10 °C

How much taller is the Eiffel Tower on the hottest day of the summer (25 °C) than the coldest day of the winter (2 °C)? The tower is 324 m tall measured from the top of the flagpole. Assume the tower is built of structural steel. (It's actually made of "puddle iron".)
The Concorde was a supersonic transport airplane (SST) in use by British Airways and Air France from 1976–2003. At its cruising speed of 2170 km/h (2.04 times the speed of sound), friction with the air would heat the airframe to 120 °C. This caused the plane to stretch by about 20 cm. The dimensions of the Concorde are 61.66×25.6×8.5 m. Assume the temperature of the airframe when Concorde is on the ground is 20 °C.
Determine the coefficient of thermal expansion of the Concorde.
Use your results from part a. to determine the material used to construct the Concorde.
A 64 liter gas tank is filled completely at 15 °C. How much gasoline overflows, if the tank heats up to 35 °C while the car is parked in direct sunlight?
A 200 liter steel water tank is filled from a horizontal inlet pipe at the bottom. A vertical overflow pipe rises vertically from the top. Both pipes are 2.0 cm in diameter. How high does the water rise in the overflow pipe if the water is heated from 15 °C to 40 °C?
A grid of thermal protection tiles on the underside of Space Shuttle EndeavourThe underside of all US space shuttle orbiters were covered in lightweight, ceramic insulating tiles. These tiles varied in size and shape, but were basically 15 cm squares spaced 1.5 mm apart (at room temperature). They were designed to withstand reentry temperatures of up to +1260 °C. What is the approximate coefficient of thermal expansion of these tiles?nation:
