Question

can anyone plz answer my questions fast and correctly with explanation​

Answer 1

Answer:

option d is correct as surface tension and viscosity decreasing with increase of temperature or vice versa

Explanation:

1. An increase in temperature of water (or any liquid) leads to an increase in kinetic energy of molecules. Thus, intermolecular forces among molecules are lowered and a decrease in surface tension is noticed.

2. The former effect causes a decrease in the shear stress while the latter causes it to increase. The result is that liquids show a reduction in viscosity with increasing temperature. With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same.

3. As the temperature of a liquid increases, the kinetic energy of its molecules also increases and as the kinetic energy of the molecules increases, the number of molecules transitioning into a vapor also increases, thereby increasing the vapor pressure.
