Why are the particles moving fast in hot drinks?
Nookie1986 [14]

temperature is defined to be the average  kinetic energy.

heat energy tends to flow from higher energy to lower energy systems, so knowing the temperatures of things tells you how heat will flow between them.

EXAMPLE --------> when you step on a very hot pavement with your bare feet that makes you move a lot faster

b) Explain what happens when a drop of concentrated sugar solution is placed on a rheo leaf peel mounted on a glass slide. Name
user100 [1]

The rheo leaf peel will lose water by osmosis and become flaccid. If the rheo leaf was boiled, this would not happen.

<h3>What is osmosis?</h3>

Across living membranes, water moves from a region of high to a region of low water potential.

Concentrated sugar solutions have low water potential when compared to the cell sap of the cells of rheo leaf peel. Thus, water will move from the rheo leaf peel to the sugar solution.

This will result in the wilting of the leaf peel.

If the leaf peel is boiled, the membranes in the cells die and can no longer function as a selectively permeable interface.
