- Which if the following statements is TRUE? A plot of V vs P for an ideal gas is a straight line with a negative slope There are no attractive forces between ideal gas molecules. At a given temperature, heavier gas particles travel more quickly than lighter gas particles. Real gases approxamate ideal gases at high pressures and low temperatures. There are strong repulsive forces between ideal gas molecules.If the trend continues as shown in the data what would the dissolved oxygen level most likely be if the temperature of the water was 35C?A cylinder of gas at room temperature (20 degrees Celsius) has a pressure P1.
