I have an unknown initial volume of gas held at a temperature of 115 K in a
container with a pressure of 6 atm. I
increase the temperature to 225 K and
decrease the pressure to 2,800 mmHg
and it causes the final volume of the gas
to be 29 L. What was the initial
volume?

answer; i believe the correct answer is (solid gold);

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

50.23 i believe is correct but don't quote me on that.
