The Trans-Alaskan pipeline stretches 1,300 km and experiences temperatures ranging from -73 degrees Celsius to 35 degrees Celsius. It is made out of steel pipes (coefficient of linear expansion 1.24 x 10-5 per degree Celsius). How much (in m) does the pipeline expand?

An automobile tire is inflated with air originally at 10.0°C and normal atmospheric pressure. During the process, the air is compressed to 27.0% of its original volume and the temperature is increased to 39.0°C. (a) What is the tire pressure in pascals? Pa (b) After the car is driven at high speed, the tire's air temperature rises to 85.0°C and the tire's interior volume increases by 3.00%. What is the new tire pressure (absolute) in pascals? Pa

When resting, a person has a metabolic rate of about 3.88 x 105 joules per hour. The person is submerged neck-deep into a tub containing 4.62 x 103 kg of water at 26.9 °C. If the heat from the person goes only into the water, find the water temperature in degrees Celsius after half an hour.

Bob built a scale model of the bridge that is 2.637m long at the lowest temperature (T=-45 degrees Celsius) using an unknown material. When the temperature reaches the highest value (T=43 degrees Celsius), he measures again the length of the bridge finding that it has expanded L=5.56mm. Calculate the coefficient of linear expansion and find the material Bob used to make his model.

Suppose you have a large hot air balloon, open at the bottom but filled with air that is heated to 50 °C while the outside air is 10 °C.  What can you say about the air inside the balloon and how much it can lift?   The density of air is surprisingly high: 1.23 kg/m3, an average hot air balloon has a volume of 3000 m3 , and the acceleration of gravity is 9.8 m/s2.     The density is  higher by the factor (273 + 50)/(273+10) = 1.14 and therefore will not have a buoyant force and will not lift off the ground with any load.       The density is lower by the factor (273 + 10)/(273+50) = 0.88 and therefore will have a buoyant force of 0.88 times the weight of the air it replaced, or about 32,000 N.        The density is lower by the factor (273 + 10)/(273+50) = 0.88 and therefore will have a buoyant force of 0.12 times the weight of the air it replaced, or about 4300 N.        The density is the same but the pressure of the hot air is higher by (273 + 50)/(273+10) =…

A steel rod and a bronze rod are heated. At zero degree Celsius, the steel rod has a Ls  and the bronze rod has a length of Lb. When the rods are heated or cooled, the difference between their length stays constant at 5.00 cm. Determine the values of Ls and Lb.

During an all-night cram session, a student heats up a 0.807 liter (0.807 x 10- 3 m3) glass (Pyrex) beaker of cold coffee. Initially, the temperature is 15.5 °C, and the beaker is filled to the brim. A short time later when the student returns, the temperature has risen to 98.0 °C. The coefficient of volume expansion of coffee is the same as that of water. How much coffee (in cubic meters) has spilled out of the beaker?

A hot air balloon uses the principle of buoyancy to create lift. By making the air inside the balloon less dense then the surrounding air, the balloon is able to lift objects many times its own weight. A large hot air balloon has a maximum balloon volume of 2090 m3. a.  If the air temperature in the balloon is 54 °C, how much additional mass, in kilograms, can the balloon lift? Assume the molar mass of air is 28.97 g/mol, the air density is 1.20 kg/m3, and the air pressure is 1 atm.

The density of lead is 1.13 x 10“ kg/m³ at 20.0°C. Find its density (in kg/m) at 131°C. (Use a = 29 x 10-° (°C)-- for the coefficient of linear expansion. Give your answer to at least four significant figures.) HINT 3 × kg/m³ 11216.1

During an all-night cram session, a student heats up a 0.304 liter (0.304 x 10- 3 m3) glass (Pyrex) beaker of cold coffee. Initially, the temperature is 18.3 °C, and the beaker is filled to the brim. A short time later when the student returns, the temperature has risen to 96.9 °C. The coefficient of volume expansion of coffee is the same as that of water. How much coffee (in cubic meters) has spilled out of the beaker?
