The coefficient of linear expansion of Aluminum is 2.3x10^-5 per deg C. The volume of an Aluminum cube, 44.0 cm on edge, will increase by what amount in cm3, if it is heated from 20.0 deg C to 70.0 deg C? 293.885

An aluminum wire is wrapped in rubber insulation. Both are subject to thermal expansion, with the following coefficients of linear expansion: alphaa=24· 10−6 1/C and alphar=8· 10−5 1/C . If the wire and insulation are the same length of 1.85m at a temperature of20.00°C, what is the difference in length (in MILLIMETERS) between the copper wire and the rubber insulation when heated up to a temperature of 189.00°C? Express a magnitude only (no negatives!). ______mm (MILLIMETERS!)

An iron rod with an initial length of 11.1 m has its temperature raised from 16o C to 30.35o C. If iron has a coefficient of thermal expansion of  12x10-6 1/oC, what is the change in length of the rod in mm?

Liquid nitrogen has a boiling point of−190.52◦C at atmospheric pressure.Express this temperature in degreesFahrenheit.Answer in units of ◦F Express this temperature in Kelvin.Answer in units of K.

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

A steel beam 12 m sits next to a concrete wall when the temp is 20 degree A gap must be left between the beam and the concrete wall for expansion purposes. If the temp rises to 45 degrees C how large must the gap be if the steel beam just touches the concrete wall? Coefficient of linear expansion of steel 12X10-6 C-1.    I thought it was 1.20X10-3 but I was wronge  a. 3.60X10-3 b. 1.20X10-3 c. 2.40X10-3 d. 5.10X10-3

1.68 L of helium gas in a balloon at room temperature (25 °C) was put in an oven at 250 °C and allowed to come to thermal equilibrium with its new surroundings. a) Calculate AU, AH, w and q for the gas inside the balloon.
