**Temperature and Kinetic Energy -
Worksheet
**

- What is the name of the branch of physics that studies the
temperature of objects and the flow of heat between objects of
different temperatures?

- Temperature is a scalar quantity with
magnitude, but no direction. Can you think of something else we
commonly measure that is also a scalar quantity?

- A gas is composed of a large number of molecules that are in
__________, __________ motion.

- When the temperature is high, the
molecules move _____________.

- What is the name of the device used to
measure temperature?

- Temperature is really a measure of the
average kinetic energy of a gas. What is the formula used for
determining kinetic energy?

- Convert these two numbers to scientific notation: 456.2332 and
0.00002349.

- Find the mass of one atomic unit of each of the following five
gasses: Hydrogen, Helium, Oxygen, Nitrogen, and
Neon.

- Assume the average velocity of oxygen at room temperature is
480 meters per second. Using the kinetic energy formula along with
your answer from question 8, calculate the kinetic energy for
oxygen.

- Assume the average velocity of nitrogen at room temperature is
510 meters per second. Using the kinetic energy formula along with
your answer from question 8, calculate the kinetic energy for
nitrogen.

- Assume the average velocity of hydrogen at room temperature is
390 meters per second. Using the kinetic energy formula along with
your answer from question 8, calculate the kinetic energy for
hydrogen.

- Write a sentence or two summarizing what you learned from this
activity.
