Consider an idealgas at 27 degrees C and1.00 atm pressure. Imaginethe molecules to be, on average, uniformly spaced, with eachmolecule at the center of a small cube.
a.) What is the length of an edge of each small cube if adjacent cubes touch but don't overlap?
b.) How does this distancecompare with the diameter of a molecule?
When she reaches the bus, explain how fast is the bus traveling? If the student's top speed is 2.20m/s^2 , will she catch the bus? What is the minimum speed the student must have to just catch up with the bus?
Suppose the cloud of atoms is cooled to one micro-Kelvin. Calculate the root mean square speed of the rubidium atoms. [The atoms are at such low density that they remain in a (metastable) gas phase].
A 15.1 mass fastened to the end of a steel wire with an unstretched length of 0.650 is whirled in a vertical circle with angular velocity 2.00 at the bottom of the circle. The cross-sectional area of the wire is 1.20×10?2 . Calculate the elongatio..
