A 15C, 2.0-cm-diameter aluminum bar just barely slips between two rigid steel walls 10.0 cm apart. If the bar is warmed to 25C, how much force does it exert on each wall?
The accurate answer is
A 15C, 2.0-cm-diameter aluminum bar just barely slips between two rigid steel walls 10.0 cm apart.
The young module depicts
The description provided that
From the expression for linear thermal expansion is:
Therefore, the final expansion will be:
The table of 18.4 depicts that the coefficient of linear thermal expansion of Aluminium is almost .
The table of 14.3 depicts that Aluminium's young modules is .
Therefore, If the bar is warmed to 25C, the force of , it exert on each wall.
To determine the mass of neon contained in a rigid, cylinder, you vary the cylinder’s temperature while recording the reading of a pressure gauge. Your data are as follows:
|Temperature (°C)||Pressure gauge (atm)|
Use the best-fit line of an appropriate graph to determine the mass of the neon.
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?
