Calculate the temperature of 4.00 moles of ideal gas at a pressure of 2.00 atm and a volume of 54.0 L. (Use 0.0821 L · atm/mol · K as the gas constant.)

- Determine what happens to the pressure of the above sample of ideal gas if the volume is halved and the temperature doubles.

A student states that if the volume of a sample of ideal gas increases to three times the original volume, and the pressure also increases to three times the original pressure, the temperature of the gas will remain unchanged.

- Explain why the student is incorrect.
- Determine the actual temperature of the ideal gas.

What are the choices?

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
