Can sound waves generate heat?

Yes, sound waves can generate heat, though usually in very small amounts

100

What is chemistry

the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.

What is the definition of Astronomy

Astronomy is the study of celestial objects, including stars, planets, galaxies, and the universe as a whole.

What does water have to do with geology

a crucial agent of geologic change

100

What is astrophysics?

a branch of space science that uses the principles of physics and chemistry to study the universe, including the origin, evolution, and properties of celestial objects like stars, planets, galaxies, and nebulae

200

Can the decay half-life of a radioactive material be changed

No, the half-life of a radioactive material is a fundamental, intrinsic property of that specific isotope and cannot be changed by external factors like temperature, pressure, or chemical environment.

200

What are atoms

the basic building blocks of matter

200

How many planets are in our solar system?

There are eight planets in our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

200

What's morphing

change smoothly from one image to another by small gradual steps using computer animation techniques.

200

What is the Big Bang theory?

explains that the universe began from a very small, hot, and dense state and has been expanding and cooling ever since, roughly 13.8 billion years ago.

300

Can you go fast enough to get enough mass to become a black hole?

No  traveling at high speeds or increasing the mass of an object will not make it a black hole

300

What are molecules

a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.


300

What is the closest star to Earth?

The closest star to Earth is the Sun.

300

Why does lava come out of volcanoes that have been quiet/dormant for so long

 magma, the molten rock beneath the surface, can build up over time and eventually overcome the pressure holding it in place, leading to an eruption.

300

What is dark matter and dark energy?

Dark matter is a hypothetical form of matter that interacts gravitationally but not electromagnetically, while dark energy is a hypothetical form of energy that is causing the universe's expansion to accelerate.

400

Can you make a shock wave of light by breaking the light barrier just like supersonic airplanes break the sound barrier

an object traveling through a material at a speed that is faster than the light in that material does indeed create an optical shock wave.

400

What is the difference between a compound and a mixture?

A compound is a substance formed when two or more elements are chemically bonded, while a mixture is a combination of two or more substances that are not chemically bonded.

400

 What is a constellation?

A constellation is a group of stars that form a recognizable pattern in the night sky.

400

Do geologists and paleontologists work together on dinosaur digs

Yes, geologists and paleontologists often work together on dinosaur digs,

400

How do stars form and evolve?

Stars form from collapsing clouds of gas and dust, and their evolution is determined by their mass and composition, eventually ending as white dwarfs, neutron stars, or black holes.

500

Can a fire have a shadow

While flames themselves don't cast shadows, the smoke and soot produced by a fire can, as well as the hot gases refracting light, creating a faint, dancing shadow-like effect.

500

What is the difference between a physical and chemical change?

 A physical change alters the form or appearance of a substance but not its chemical composition, while a chemical change results in the formation of new substances with different properties.

500

What is a black hole?

A black hole is a region of spacetime with such strong gravity that nothing, not even light, can escape its pull.

500

How much does petrified wood weigh

160-200 pounds per cubic foot.

500

What is the fate of the universe?

The fate of the universe depends on the amount of dark energy and dark matter it contains, with possibilities ranging from continued expansion to eventual collapse.
