A pressure gauge measures the pressure of your bike tires by connecting to the inside of the tire via a small tube. The reading shows six atmospheres. If you were to replace that tube by another one that has twice the diameter of the original, what pressure would you read?
Homework Answers
Pressure is inversely proprtional to diameter. So as the diameter is doubled, the pressure is halved.

A. Which of the following statements is true for a gas contained in a box with a piston? 1. Some but not all isothermal expansions are adiabatic. 2.An isothermal expansion is never adiabatic. 3.Every isothermal expansion is adiabatic. 4.Every expansion is either isothermal or adiabatic. B. Doubling the gauge pressure of an ideal gas, while keeping the volume of the gas fixed, implies that the temperature changes how? There is not enough information to solve this. The temperature halves The...

5. If you put air in your tires in La Paz, Bolivia, and your pressure gauge is reading 25 psig, what is the absolute pressure inside the tire, in psia? (The standard atmospheric pressure in La Paz is about 62 kPa!) Answer: between 30 and 35 psia. 2. A manometer like the one we drew in class has water in the column. The side that is open to standard atmospheric pressure is 20 cm lower than the side open to...

Inside your smartphone is a small integrated circuit called a "Hall sensor" that measures the magnetic field to fairly high precision. (It is actually made of three separate "Hal bars", to measure the field components in the r, y, and z directions). The Hall sensor acts like a compass for your phone, and assists in navigation and GPS apps. Let's assume each Hall bar is a strip that is 20 11m long, 5 ㎛ wide, and 1 μm thick. (a)...

A single atom moves at a high rate of speed inside of a small box that is otherwise evacuated. The box is a cube, with the length of each side being L = 10 cm. The atom's collisions with the sides of the box are elastic. The force F(t) on one of the six sides is (hypothetically) monitored as a function of time, and a qualitative graph of F vs t is shown in the figure. Each narrow spike in...

Your boss would like to connect a high temperature and pressure stream of steam (from another unit at the plant site) to a turbine that will be operated adiabatically and will serve as an energy source for a small electric generator. The steam is at T1 = 600 C and P1 = 10 bar. The outlet conditions of the turbine must be T2 = 400 C and P2 = 1 bar. The inlet diameter to the pipe connecting to the...

An Alka-Seltzer tablet consists of NaHCOs (sodium bicarbonate), citric acid (H3C&HsO; citric acid is triprotic), aspirin and other inert ingredients. When dissolved in water, citric acid and NaHCO3 components react as follows: In the first part of the experiment, we will determine the mass of NaHCO in a tablet of Alka Seltzer. To do this, we will use a known mass of a powdered sample of Alka-Seltzer and determine the mass of CO2 gas...
