A closed, rigid tank having a volume of 3 m3 contains moist air in equilibrium with liquid water at 808C. The respective masses present initially are 10.4 kg of dry air, 0.88 kg of water vapor, and 0.17 kg of liquid water. If the tank contents are heated to 1608C, determine

Regular reflections occurs when light reflects off a very smooth surface and forms a clear image.
Diffuse reflection: occurs when light reflects off a rough surface and forms a blurry image or no image at all.

Similarities: they both hit the surface, but the difference is one of them give clear image the other one gives blurry image or no image at all.

Hope this helped!
