लैंगमुइर अधिशोषी समतापी (Langmuir adsorption isotherm) के अनुसार, pV बनाम दाब 'p' का ग्राफ एक सीधी रेखा देता है, जिसकी ढाल (slope) किसके बराबर होती है?

Adsorption of a gas on a solid follows the Freundlich adsorption isotherm. A plot of logxm (on the y-axis) vs log p (on the x-axis) gives a straight line with a slope (1/n) equal to 3 and an intercept (log k) equal to 0.30. What is the value of xm at a pressure of 2 atm? (Given: log10(2) = 0.30)

Which of the following colloids is NOT classified as a gel?
