1. The Eiffel Tower in Paris is 984.5 ft tall and is made mostly of steel.

a) If this is its height in summer when its temperature is 35.00C, by how much the vertical distance shorten if you decide to climb it during a winter when its temperature is - 5.00C?

b) Express the coefficient of linear expansion of steel in terms of Kelvin scale and Fahrenheit degrees.

2. A copper pot with a mass of 0.500 kg contains 0.150 kg of water, and both are at a temperature of 20.00C. A 0.250 kg block of iron at 90.00C is dropped into the pot. Find the final temperature of the system, assuming no heat loss to the surroundings.
