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!)
Step 1 (a) The ideal-gas equation describes each condition of the air in the tire. We will set up ratios in order to describe these changes. Dividing the equations PV = nRT in the initial and final states, we have PfVf Tf P¡Vi Ti Solving for the final pressure in the tire, gives Pf = = = which gives I Tf P(V)() P₁ Vf T₁ = (1.013 x 105 Pa) x 105 Pa. Note that the volume V¡ cancels out of the equation. = Vf Po = Pr (V ( ) ( ) Pd Pf Vi V₁ Step 2 (b) After the car is driven, the temperature and volume of air in the tire have changed. Let Td be the temperature and Vd be the volume of air in the tire. We have PdVd Td PfVf Tf' x 105 Pa 273 + 273 + Vf Vf Again we see that the volume Vf cancels out of the equation. °C K °℃ K = x 105 Pa.
You are given a frozen sample of an unknown substance. The sample has a temperature of 4K and a mass of 10g. You put the frozen sample in a closed container of volume 10L and heat it slowly to 120degC. At this point, the complete sample has evaporated and is in the gas phase. You measure a pressure of 117kPa inside the container. Which substance is it?
A bubble having a diameter of 62 cm is re- leased from a depth of 4.6 m from the bottom of a swimming pool. The temperature of the water at the surface is 21°C, whereas it is 15°C at the point of release. What will the diameter of the bubble be when it reaches the surface? The acceleration of gravity is 9.8 m/s² and the density of water is 1000 kg/m³. Answer in units of cm.

Twenty-five milliliters of liquid nitrogen (density = 0.807 g/mL) is poured into a cylindrical container with a radius of 10.9 cm and a length of 20.3 cm. The container initially contains only air at a pressure of 760.0 mmHg (atmospheric pressure) and a temperature of 298 K. If the liquid nitrogen completely vaporizes, what is the total force (in lb) on the interior of the container at 298 K ? ΜΕ ΑΣΦ ? F = lb
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.

Warm air flows through a rectangular, uninsulated heating duct in your cold attic during the winter. The air has a mass flow rate of 0.47 kg/sec, and the heating duct has dimensions of 20.0cm by 28.0cm with a length of L = 9.60m. The inlet temperature of the air is 42.0°C, at a pressure of 1.00 atm. Your cold attic keeps the surface temperature of the duct at a temperature of 8.0°C. Find the heat transfer rate.
Before leaving on a trip to Melbourne Beach, Florida, you measure the pressure inside the tires of your car at a gas station. At – 7.5 C (chilly!), the tire pressure is 206.5 kPa. When you arrive in Florida, you check the tire pressure and find it is now 236.5 kPa. What is the temperature in Melbourne Beach?
