Slow cooling of hot magma leads to the formation of ___________ crystals
Answer:
Slow cooling leads to the formation of large crystals. If the crystals remain undisturbed while cooling, they grow according to a regular pattern. Magma closer to the surface cools much faster than magma that hardens deep below ground. With rapid cooling, there is no time for magma to form large crystals.

How does the development of the heliocentric model show how scientific ideas change over time?
Answer: Italian scientist Giordano Bruno was burned at the stake for teaching, among other heretical ideas, Copernicus' heliocentric view of the Universe. In 1543, Nicolaus Copernicus detailed his radical theory of the Universe in which the Earth, along with the other planets, rotated around the Sun.

What is Heliocentric model?Copernicus' heliocentric view of the Universe. In 1543, Nicolaus Copernicus detailed his radical theory of the Universe in which the Earth, along with the other planets, rotated around the Sun.
Because of heliocentrism, we now understand that Earth and the other planets of the solar system all orbit the sun.
But there once was a theory that put Earth at the centre of what was thought to be the entire cosmos and that everything literally revolved around us. The sun is at the centre of the heliocentric model, which is now known as the geocentric model.
Therefore, Italian scientist Giordano Bruno was burned at the stake for teaching, among other heretical ideas.

In a chemical reaction, which of the following is true of the products?
A. The products have the same shape as the reactants.
B. The products have the same physical properties as the reactants.
C. The products have the same state of matter as the reactants.
D. The products have the same number atoms as the reactants.
The correct statement about the chemical reaction is "the products have the same number atoms as the reactants."
What is chemical reaction?A chemical reaction occurs when one or more reactants (also known as reactants) are changed into one or more products (also known as products).
Chemical transformation occurs as a result of this process, which involves the breaking and forming of chemical bonds.
Rust is formed when iron and oxygen combines with each other.
Only the atoms present in the reactants can end up in the products of a chemical reaction. There are no new atoms formed, and no atoms destroyed.
In a chemical reaction, the reactants and products have the same atoms, but they are rearranged during the reaction. As a result, the atoms in the products end up in various combinations. As a result, the products are new chemically distinct substances from the reactants.
Hence, the correct statement is option D.

A submarine fills a special storage area known as ballast with water in order to increase its density. This allows it to dive deeper into the ocean. When a submarine needs to rise rapidly, compressed air is used to push the water out of the ballast. What effect does replacing the water in the ballast with air have on the submarine?
Answer:
The submarine will rise.
Explanation:
To get a submarine to surface, the main vents in the top of the tank are closed and high-pressure compressed air is blown into the ballast tanks, forcing the water out through the flood ports at the bottom of the tank. This increases the vessel's displacement.
