A nebula—a region of the galaxy where new stars are forming—contains a very tenuous gas with . This gas is heated to by ultraviolet radiation from nearby stars. What is the gas pressure in atm?
The U-shaped tube in FIGURE P18.57 has a total length of . It is open at one end, closed at the other, and is initially filled with air at pressure.
Mercury is poured slowly into the open end without letting any air escape, thus compressing the air. This is continued until the open side of the tube is completely filled with mercury. What is the length of the column of mercury?
At what temperature does the numerical value in °F match the numerical value in °C?
A gas at fills volume . If the pressure is held constant, what is the volume if
(a) the Celsius temperature is doubled and
(b) the Kelvin temperature is doubled?
An electric generating plant boils water to produce high-pressure steam. The steam spins a turbine that is connected to the generator.
a. How many liters of water must be boiled to fill a 5.0 m3 boiler with 50 atm of steam at 400C?
b. The steam has dropped to 2.0 atm pressure at 150C as it exits the turbine. How much volume does it now occupy?
