Part 2 needed!
An ideal gas at temperature T₀ is slowly compressed at a constant pressure of 2 atm from a volume of 10 liters to a volume of 2 liters.
Then the volume of the gas is held constant
while heat is added, raising the gas temperature back to T₀
1 atm = 1.0×10⁵ Pascals and 1 liter = 0.001 m³
Part 1:
Calculate the work done ON the gas.
The answer to the first part is
1. −800 J
2. −400 J
3. +400 J
4. +1600 J
5. −1600 J
6. +800 J
+1600 J (I have this part already)
I converted the liters to .010 m³(V₀) and .002 m³(Vₓ) (final)
and 2 atm to 2.0 * 10⁵ Pa (pressure)
W=-p(Δv)
Work= negative pressure (final-initial Volume)
-2.0*10⁵(2-10)= +1600 J
**Part 2: Is the one I need
Calculate the heat flow INTO the gas
1. +800 J
2. −1600 J
3. −400 J
4. +1600 J
5. +400 J
6. −800 J
I don't understand the formula of the Universal Ideal Gas Law
ΔU= Q+W and how to apply it to this question, Help!**
Work is W and Q is the heat I believe and applied, all I know is it has to become
Q=-W

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.
