🌊Viscosity of a liquid decreases with temperature.
💧Surface tension is the force acting on the surface of a liquid due to intermolecular interactions.
🌌The rise of liquid in capillary tubes is a result of intermolecular forces and the angle of contact.
⚡️Excess pressure in a liquid drop is caused by a pressure difference between the inside and outside of the drop.
📏Surface energy and work are related through the change in surface area.
How does viscosity change with temperature?
—Viscosity of a liquid decreases with an increase in temperature.
What is surface tension?
—Surface tension is the force acting on the surface of a liquid due to intermolecular interactions.
Why does liquid rise in capillary tubes?
—The rise of liquid in capillary tubes is a result of intermolecular forces and the angle of contact between the liquid and the tube.
What is excess pressure in a liquid drop?
—Excess pressure in a liquid drop is the pressure difference between the inside and outside of the drop.
How are surface energy and work related?
—Surface energy and work are related through the change in surface area.
