What is Glucose + Oxygen → Carbon dioxide + water + ATP

What is Cellular Respiration

300

The process where warm air rises and cools, forming clouds and precipitation.

What is convection

300

Why does food color spread faster in hot water compared to cold water?

What is because particles move faster in hot water, causing quicker mixing?

500

In this type of chemical reaction, a compound breaks down into two or more simpler substances.

What is Decomposition

500

A front formed when a cold front flows right behind a warm front, and another cool air mass pushes into the warm air mass.

What is occluded Front

500

This is the particle formed when atoms gain or lose electrons.
