which property of water allows a paper towel to pick up a puddle of water
Which property explains the ability of a water strider to walk on water? Which property is demonstrated when paper towels absorb a water spill? Water has high specific heat.
Which property of water allows a water strider?
Surface tension allows a water strider to “walk on water”
Which of the following is a property of water that allows a water strider to walk on the surface of water quizlet?
Which property of water allows a water strider to walk on water? Water’s high surface tension, related to its cohesion, makes water behave as though coated with an invisible film. You just studied 5 terms!
What is responsible for the properties that let a water strider run on water without breaking the surface?
The high surface tension resulting from this collective strength of hydrogen bonds allows organisms such as the water strider to walk, stand, or run on a pond without breaking the surface.
What property allows plants to pull water upward from their roots to their stems and leaves?
The cohesive properties of water (hydrogen bonding between adjacent water molecules) allow the column of water to be ‘pulled’ up through the plant as water molecules are evaporating at the surfaces of leaf cells. This process has been termed the Cohesion Theory of Sap Ascent in plants.
Which property of water causes it to cling to other water drops and form a giant bubble on a penny?
The attraction of water molecules to other substances, like soil or glass, is called adhesion. As drops of water are added onto a penny, the adhesive force between the water and the penny keeps the water from falling off. Cohesive forces are strong, but not unbreakable.
What property of water allows insects to walk on water?
The weight of the insect and structure of their feet in combination with the surface tension of water allow some insects to walk on water. Water molecules are more attracted to each other than they are to other materials, so they generate a force to stay together called surface tension.
What property of water allows water spiders to walk across the surface of a pond?
high surface tension of water, from collective strength of hydrogen bonds, allows this raft spider to walk on the surface of a pond.
How do water striders move?
The water strider’s secret is its legs. The legs have tiny hairs that repel water and capture air. By repelling water, the tiny water striders stand on the water’s surface and the captured airs allows them to float and move easily.
Which of the following properties of water enables it to move from the roots to the leaves of plants?
Cohesion and adhesion form an attraction called capillary action. This allows for movement of water from roots to the xylem tubes of plants, and up, against the force of gravity. Transpiration, or the evaporation of water from plant leaves provides an additional pull of water up the plant from roots to leaves.
What property of water allows a high boiling point?
Cohesion and hydrogen bonding are the cause for water’s low vapor pressure, high boiling point, and high heat capacity. Adhesion is water’s property to adhere to a surface, and is the cause of capillary action.
Which of the following is a hydrophobic material?
Answer: Examples of hydrophobic molecules include the alkanes, oils, fats, and greasy substances in general. Hydrophobic materials are used for oil removal from water, the management of oil spills, and chemical separation processes to remove non-polar substances from polar compounds.
Which of the following is a property of water?
The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling.
What is responsible for the cohesive property of water?
Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.
Which of the following is not property of water?
Explanation: Water can moderate temperature because of the two properties: high-specific heat and the high heat of vaporization. Hence, all the above given options are not the properties of water.
How do plants transport water upwards?
Water from the soil enters the root hairs by moving along a water potential gradient and into the xylem through either the apoplast or symplast pathway. It is carried upward through the xylem by transpiration, and then passed into the leaves along another water potential gradient.
What is the property of droplets of water on the leaf?
The water drop is composed of water molecules that like to stick together, an example of the property of cohesion. The water drop is stuck to the end of the leaf, which is an example of the property of adhesion.
How do plants pull water up?
The tension created by transpiration “pulls” water in the plant xylem, drawing the water upward in much the same way that you draw water upward when you suck on a straw. Cohesion (water sticking to each other) causes more water molecules to fill the gap in the xylem as the top-most water is pulled toward the stomata.
