Your car's radiator is made of steel and is filled with water. You fill the radiator to very top with water, then drive off without remembering to replace the cap. As the water and steel radiator heats up, will the level of water drop or rise and overflow? Explain? To answer this question, first you will have to investigate what a radiator is and what purpose is it serves in a car?

Incandescent lightbulbs are filled with an inert gas to lengthen the filament life. With the current off ( at T = 20.0 degrees Celsius ), the gas inside a lightbulb has a pressure of 113 kPa. When the bulb is burning, the temperature rises to 89.4 degrees Celsius. What is the pressure at the higher temperature?

Large helium-filled balloons are used to lift scientific equipment to high altitudes. a) What is the pressure, in atmospheres, inside such a balloon if it starts out at sea level with a pressure of one atmosphere and a temperature of 10.0°C and rises to an altitude where its volume is twenty times the original volume and its temperature is -49.5°C ?  b) What is the gauge pressure, in atmospheres, in the balloon then? (Assume the atmospheric pressure is constant.)

Amanda discovers that the gauge pressure in her car tires is 2.50 ×105 Pa at a temperature of 35.0oC. The average volume of a single tire at that temperature is 10.0 L. 1.) Find how many moles of gas (air) are in one of Steve’s tires.   2.) Later Amanda travels to a place where the temperature is –40.0oF. She notices that the tires are looking low and estimates that each tire has lost approximately 1.0 L of its volume. What is the gauge pressure in the tire now?

A closed system consisting of 2 lb of a gas undergoes a process during which the relation between pressure and volume is pV" = constant. The process begins with p₁ = 25 lbf/in², V₁ = 13 ft³ and ends with p2 = 100 lbf/in². The value of n = 1.3. Determine the final volume, V₂, in ft3, and determine the specific volume at states 1 and 2, in ft³/lb.

An ideal gas is kept at constant pressure while increasing its volume from an initial volume of 2 liters to a final volume of 6 liters. The initial temperature of the gas is 300K, what is the final temperature? O 100K O 900K O 1200K O 300K O oo O

In this problem you will consider the effect that thermal expansion due to temperature will have on Archimedes' principle. Take the densities of water and copper at 0ºC to be 1.00 × 103 kg/m3 and 8.90 × 103 kg/m3, respectively. a.  Calculate the fraction of a copper block’s weight that is supported by the buoyant force at 0°C.  b. Calculate the fraction of a copper block’s weight that is supported by the buoyant force at 95°C. Assume the volume expansion coefficient of copper is βC = 5.10 × 10-5 1/°C.

A container holds 0.420 m3 of oxygen at an absolute pressure of 3.80 atm. A valve is opened, allowing the gas to drive a piston, increasing the volume of the gas until the pressure drops to 1.40 atm. If the temperature remains constant, what new volume (in m') does the gas occupy? HINT m3 Need Help? Read It Watch It

Answers (~1.9kJ, ~1.1kJ, ~4kJ) The figure to the right shows a gas contained in a vertical piston-cylinder assembly. A vertical shaft with a cross- sectional area of 1.0 cm² is attached to the top of the piston. The total mass of the piston and shaft is 35 kg. While the gas is slowly heated, the internal energy of the gas increases by 0.25 kJ, the potential energy of the piston-shaft combination increases by 0.5 kJ, and a force of 1300 N is exerted on the shaft as shown in the figure. The piston and cylinder are both good insulators and friction between them is negligible. The local atmospheric pressure is 1 bar and g = 9.81 m/s². Determine: 21 F-1300N (c) the heat transfer to the gas (kJ) (d) Provide a detailed accounting of where all of the heat energy has gone. C 19 4 A-14cm (a) the work done by the shaft (kJ) (b) the work done in displacing the atmosphere (kJ) (atmosphere does not act on shaft aka a donut area) D²10.0
