How would a rock's weight on the Moon or the Sun compare to its weight on Earth? Assume

 on Earth, a 5.0-kg object weighs 49 N; on the Moon, where g is 1.67m/s2 1.67 m/s 2 , the object weighs 8.4 N.

Explanation:

The sun is 27.9 times heavier the moon is 16.5% of it on earth

Explanation:

On the moon, there is less gravity pulling on objects, so they weigh less. For example, a rock that weighs one pound while on Earth will weigh less than that if it is taken to the moon.

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.
