What is condensation?
- Condensation is a process of boiling
- Condensation is a process in which a liquid changes into gas
Correct Answer

A. Condensation is a process in which a liquid changes into gas

Explanation

Condensation is the process through which a substance transitions from its gaseous state to its liquid state. It occurs when the temperature of the gas decreases, causing the particles to slow down and come closer together, eventually forming a liquid. This process is the opposite of evaporation, where a liquid changes into a gas.

Everything is made up of

Correct Answer
atoms, Atoms

Explanation
Everything is made up of atoms. Atoms are the fundamental building blocks of matter, consisting of a nucleus (composed of protons and neutrons) surrounded by electrons. They combine in various ways to form molecules, which in turn make up the substances and materials around us. This atomic structure is the basis of all physical matter, whether it is solid, liquid, gas, or plasma.

A substance that is made up of some kind of atom only is called an .

Correct Answer
compound
atom
element

Explanation
A substance that is made up of some kind of atom only is called an element. An element is a pure substance consisting of only one type of atom. Compounds, on the other hand, are substances made up of two or more different types of atoms chemically bonded together. Atoms are the basic building blocks of matter and are the smallest unit of a chemical element that retains the chemical properties of that element.

What is geology?
- The study of living things
- The study of substances
- The study of matter,energy and natural forces
- The study of the sun,moon and the stars
- The study of structures of the earth
Correct Answer

A. The study of structures of the earth

Explanation

Geology is the study of structures of the earth. It focuses on understanding the composition, processes, and history of the Earth's materials, including rocks, minerals, and the various layers of the Earth's crust. Geologists examine the formation of mountains, volcanoes, and other geological features, as well as the forces that shape the Earth's surface over time. They also study the Earth's history through the analysis of fossils and other geological evidence. By studying the structures of the Earth, geologists gain insights into the planet's past and present, and can make predictions about future geological events.

Why is carbon an element?
- Because it is made up of different kinds of atoms
- Because it is made up of same kind of atom
Correct Answer

A. Because it is made up of same kind of atom

Explanation

Carbon is an element because it is made up of the same kind of atom. Elements are substances that cannot be broken down into simpler substances by chemical means, and they consist of only one type of atom. In the case of carbon, it is composed solely of carbon atoms. This characteristic distinguishes carbon as an element rather than a compound, which consists of different types of atoms bonded together.

What is distillation?
- The process of boiling and condensing water
- The process in which a liquid changes into gas
Correct Answer

A. The process of boiling and condensing water

Explanation

Distillation is the process of separating mixtures based on the differences in their boiling points. It involves heating a liquid (in this case, water) to its boiling point, which causes it to vaporize. The vapor is then cooled and condensed back into a liquid, resulting in the separation of the desired substance from impurities or other components. In the context of water, distillation is commonly used to purify and remove contaminants, producing clean and drinkable water.
