Chemistry
What is the name of the table that organizes all the known elements?
Periodic Table. The periodic table is a chart that groups elements by their chemical properties.
What is the force that pulls objects towards the Earth?
Gravity. Gravity is a fundamental force that attracts any two objects with mass.
What type of electromagnetic wave has the longest wavelength and is used in radio broadcasts?
Radio Waves. Radio waves have the longest wavelengths and lowest frequencies in the electromagnetic spectrum.
What is the largest planet in our solar system?
Jupiter. Jupiter is a gas giant and is many times more massive than all the other planets combined.
This gas is essential for life and makes up about 78% of Earth's atmosphere.
Nitrogen. Nitrogen is a colorless, odorless gas that is crucial for plant growth and protein synthesis.
The study of motion and its causes is called...?
Mechanics. Mechanics is a branch of physics that deals with the motion of objects and the forces that cause them to move.
This type of wave is used in medical imaging and security scanners. it is called...?
X-rays. X-rays are a type of electromagnetic wave with a high frequency and short wavelength that can penetrate through some materials.
This giant ball of hot gas is the center of our solar system.
The Sun. The Sun is a star that provides light and heat to the planets in our solar system.
When baking a cake, what is the white powder that helps it rise?
Baking Soda. Baking soda (sodium bicarbonate) reacts with an acid to release carbon dioxide gas, which makes the cake rise.
The measurement of how hot or cold something is called...?
Temperature. Temperature is a measure of the thermal energy of a system.
The type of wave you see with your eyes is called...?
Visible Light. Visible light is a narrow range of electromagnetic waves that our eyes can detect.
The first person to walk on the Moon was...?
Neil Armstrong. Neil Armstrong was the commander of the Apollo 11 mission and the first human to set foot on the Moon in 1969.
What sour-tasting liquid is produced by the fermentation of sugars by bacteria and yeasts?
Vinegar. Vinegar is a sour-tasting liquid produced by the fermentation of sugars by bacteria and yeasts. It is commonly used as a condiment or preservative.
What is the transfer of thermal energy through direct contact?
Conduction. Conduction is the transfer of thermal energy through direct contact between two objects with different temperatures. For example, when you hold a hot cup of coffee, heat is transferred from the cup to your hand by conduction.
What part of the electromagnetic spectrum is used in microwave ovens to cook food?
Microwaves. Microwaves are a type of electromagnetic radiation with a wavelength longer than radio waves and shorter than infrared radiation. Microwave ovens use microwaves to heat food by causing the water molecules in the food to vibrate.
What type of chemical reaction releases energy in the form of heat or light?
Exothermic reaction. An exothermic reaction is a chemical reaction that releases energy to its surroundings, often in the form of heat or light. Combustion is a common example of an exothermic reaction.
What is the force that opposes the motion of an object through a fluid?
Drag. Drag is a force that opposes the motion of an object through a fluid (liquid or gas). It is caused by the friction between the object and the fluid molecules.
what type of waves are used in medical imaging techniques like X-rays?
X-rays (Explanation: X-rays are a type of electromagnetic radiation with shorter wavelengths and higher frequencies than visible light. They are used in medical imaging to see through soft tissue and reveal bones.)
