A) gase decreases and liquid increases
B) gase increases and liquid decreases
C) gase and liquid increases
D) gase and liquid decreases

Solution :
Viscosity in gases arises principally from the molecular diffusion that transports momentum between layers of flow. For gases viscosity increases as temperature increases, while in liquids the additional force between molecules become important, hence viscosity tends to fall as temperature increases.
