Exam 10: Temperature and Kinetic Theory

Due to the unusual thermal expansion properties of water, when a lake freezes during the winter, the water at the bottom of the lake is at ________ temperature than the water above it.

Express 45° C in °F.

A confined gas has an average energy/molecule of 60. meV. If the pressure is tripled and the volume is reduced by a factor of 3, what now is the average energy?

Given the following four speeds (in m/s) 16.0, 22.0, 36.0, and 38.0: (a) what is the average speed? (b) what is the rms speed?

A temperature change of 20 C° corresponds to a temperature change of

The surface water temperature on a large, deep lake is 3° C. A sensitive temperature probe is lowered several m into the lake. What temperature will the probe record?

A constant pressure gas thermometer is initially at 28.° C. If the volume of gas increases by 10%, what is the final Celsius temperature?

The universal gas constant has what units?
