Which of the following explains why hot liquids have a greater average energy of motion than cold liquids? * hot liquids have more electrons cold liquids have more electrons. particles in hot liquids move faster than particles in cold liquids particles in cold liquids move faster than particles in hot liquids.

Particles in hot liquids move faster than particles in cold liquids. The faster a particle moves, the greater its kinetic energy.

The number of electrons in a particle has nothing to do with its kinetic energy.

Particles in cold liquids move more slowly than particles in hot liquids.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
