What is the difference between transpiration pull and capillary action? Capillary action is the attraction between water molecules and the walls of the xylem vessels, causing water movement upwards through the roots, stem and into the leaves. Transpiration pull is when the loss of water from the leaves called transpiration causes water to be pulled […]

How would you change the distance between two charged particles?
What affects the strength of van der Waals forces?
What affects the strength of van der Waals forces? Number of Electrons Held by the Atoms/Molecules The greater the number of (instantaneous) dipoles formed, the greater the strength of the Van der Waals force. What are the three types of van der Waals forces? van der Waals forces may be classified into three types: electrostatic, […]
What happens to bimetallic strip when heated?
What happens to bimetallic strip when heated? When this bimetallic strip is heated, the brass expands more than the steel and the strip curves with the brass on the outside. If the strip is cooled, it curves with the steel on the outside. Bimetallic strips are used as switches in thermostats. Why is a bimetallic […]
Does force equal mass times velocity?
Does force equal mass times velocity? The first equation states that a Force is equal to Mass times Acceleration, or Newton’s second law of motion. The second one states that Momentum (P) is equal to Mass times Velocity. You can see that the difference lies between velocity and acceleration: acceleration is the rate of change […]
How the concentration affects the rate of reaction?
How the concentration affects the rate of reaction? Concentration. If you increase the concentration of a reactant, there will be more of the chemical present. More reactant particles moving together allow more collisions to happen and so the reaction rate is increased. The higher the concentration of reactants, the faster the rate of a reaction […]
Is water soluble in water?
Is water soluble in water? Liquids are miscible or immiscible… So, water does not dissolve in water. What are 2 things that would not dissolve in water? Many substances will not dissolve in water, including oil, paraffin wax and sand. What can water not dissolve? Sugar, sodium chloride, and hydrophilic proteins are all substances that […]
What are observable and measurable properties of matter?
What are observable and measurable properties of matter? Observable properties include measurements like height, weight, temperature, and the volume of an object. Explanation: Observable properties are things we can use our five senses to determine, the measurable properties in the question need a tool like a thermometer or a ruler to determine. What are the […]
