Consider a container of volume 5.0 dm3 that is divided into two compartments of equal size. in the left compartment there is nitrogen at 1.0 atm and 25°c; in the right compartment there is hydrogen at the same temperature and pressure. calculate the entropy and gibbs energy of mixing when the partition is removed. assume that the gases are perfect.

On a cold day, when the air temperature is 0°c, you empty your lungs and take a deep breath, filling your lungs with 4.2 l of air. if you hold your breath until the temperature of the air in your lungs reaches 37°c, what is the volume of the air in your lungs at that point, assuming the pressure does not change?

In order for the bug to fly through the air a force has to push the bug forward. identify this force. how does the bug produce

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
