Question

what distinguishes waters cohesive properties from oil? * 5 points
oil has stronger hydrogen bonds
water has weaker intermolecular forces
water has hydrogen bonds while oil does not
oil and water have identical cohesive properties
how does cohesion assist in plant water transport? * 5 points
it prevents water from moving up the plant
it creates a continuous stream of water molecules moving upward
it breaks the water molecules apart
it only works in the roots
what is surface tension in water? * 5 points
the breaking of water molecules
the mixing of water with air
the tension between unlike molecules
the inward pull of surface water molecules creating a skin - like layer

Explanation:

1. Water has hydrogen - bonding between its molecules which is a strong intermolecular force. Oil is non - polar and does not have hydrogen bonds.
2. Cohesion in water allows water molecules to stick together, creating a continuous column that moves upward in plants during transpiration.
3. Surface tension in water is due to the inward pull of surface water molecules, creating a "skin - like" layer.

Answer:

1. Water has hydrogen bonds while oil does not
2. It creates a continuous stream of water molecules moving upward
3. The inward pull of surface water molecules creating a "skin - like" layer
