Frequently Asked Questions
What is the difference between a physical change and a chemical change?
A physical change alters the form or appearance of a substance without changing its composition, such as melting ice. A chemical change results in the formation of new substances, like rust forming on iron.
What are the three states of matter and how do they differ?
The three states of matter are solid, liquid, and gas. Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have neither definite shape nor volume.
How does the scientific method help in conducting experiments?
The scientific method provides a systematic approach for investigating phenomena, allowing scientists to formulate hypotheses, conduct controlled experiments, collect data, and draw conclusions based on evidence.
What is the role of photosynthesis in the ecosystem?
Photosynthesis is the process by which plants convert sunlight into chemical energy, producing glucose and oxygen. It is essential for the ecosystem as it provides food for plants and oxygen for animals.
What are the basic building blocks of matter?
The basic building blocks of matter are atoms, which consist of protons, neutrons, and electrons. Atoms combine to form molecules, which make up all substances.
What is Newton's First Law of Motion?
Newton's First Law of Motion states that an object at rest will remain at rest, and an object in motion will continue in motion at a constant velocity, unless acted upon by a net external force.
