Pls.. me with this i really need it.. pls. a gas in a cylinder expands from a volume of 0.110 m3 to 0.320 m3. heat flows into the gas just rapidly enough to keep the pressure constant at 1.65 x 105 pa during the expansion. the total heat added is 1.15 x 105 j. (a) find the work done by the gas. (b) find the change in internal energy of the gas. (c) does it matter whether the gas is ideal? why or why not?

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.

The flame produced by the burner of a gas (propane) grill is a pale blue color when enough air mixes with the propane (c3h8) to burn it completely. for every gram of propane that flows through the burner, what volume of air is needed to burn it completely? assume that the temperature of the burner is 195.0°c, the pressure is 1.05 atm, and the mole fraction of o2 in air is 0.210.
