Explanation

• Surface tension decreases as temperature increases.
• Higher temperature increases the kinetic energy of liquid molecules, weakening the effect of intermolecular cohesive forces at the surface.
• Surface tension becomes nearly zero at the critical temperature, where the distinction between liquid and gas disappears.
• Water has a surface tension of approximately 72.8 mN/m at 20°C.

Explanation

• Dew point temperature is the temperature at which air becomes saturated when cooled at constant pressure without changing its water-vapour content.
• At the dew point, actual vapour pressure equals saturated vapour pressure, and condensation begins if cooling continues.

Explanation

• Iron (Fe) is an immobile or poorly mobile nutrient in plants.
• Its deficiency commonly causes interveinal chlorosis (yellowing between the veins) in young leaves.

Additional information:

• Iron is a micronutrient required for chlorophyll formation and several plant enzyme processes.
• Iron deficiency is common in calcareous soils, where high soil pH reduces iron availability.
