Q1: The rough value of diffusion co-efficient of water vapor into air at 25°C may be about __________ cm2/sec.A 0.25
B 2.5
C 1.25
D 0.0025
ANS:A - 0.25 The rough value of the diffusion coefficient of water vapor into air at 25°C is approximately 0.25 cm²/sec. Diffusion coefficients can vary depending on factors such as temperature, pressure, and the specific gases involved. However, for rough estimations, a value around 0.25 cm²/sec is commonly used for the diffusion coefficient of water vapor into air at 25°C under typical atmospheric conditions. |
