Answer:
Hot water rises and cold water sinks is a model of thermal energy transfer by conduction.
Water breaks down into hydrogen and oxygen: It is a decomposition reaction as a single substance decomposes to give two products.

Leaves make starch using chlorophyll and carbon dioxide: Synthesis reaction: as the synthesis reaction involves two or more than two reactants which join together to result into a single main product along with the formation of simple by products.

Food burns in oxygen gas and releases a lot of energy: Combustion: Combustion process involves the use of oxygen to give products along with release of energy.

Adding vinegar (acid) to baking soda (alkali) gives a product that is neither acidic nor alkaline: Neutralization: acetic acid in vinegar reacts with soda (base) to give salt (neutral) and .

Answer:
wrong answer because m=100
Answer:
A bowling ball stored on a high shelf has more potential energy
A base ball on the same shelf should rather fall on my head
Explanation:
Potential energy =mgh where m= mass, g= gravitational force and h is height
The bowling ball is bigger and heavier than the base ball
which means more mass . The remaining parameters are constant.
This means the bowling ball has more potential energy.
Since the base ball is lighter then it’s preferable to land on someone’s head due to the lesser force it will expert and lesser pain too.
