Hello!
The answer to your question is.
True. Coal is NOT considered a mineral because it is organic and made from the remains of once living things.
~Hope this Helps!~
The answer is A because potential energy is stored up energy which means that it’s not moving
Answer:
When a number is written in scientific notation (representing the number using powers of base ten) it is expressed so that it contains a digit in the place of the units and all other digits after the decimal point, multiplied by the respective exponent. For example, the number
.
On the other hand, it is known the units in the SI for mass, length, time and temperature are kilogram (kg), meter (m), second (s) and Kelvin (K), respectively. In addition, thera are prefixes of the International System (SI) that indicate a specific factor of 10.
For example:
-Giga (G) is a prefix that indicates a factor of 
-Pico (p) is a prefix that indicates a factor of 
-Mili (m) is a prefix that indicates a factor of 
-Micro (
) is a prefix that indicates a factor of 
-Tera (T) is a prefix that indicates a factor of 
-Kilo (K) is a prefix that indicates a factor of 
Knowing this, let's express these quantities in terms of the SI base units:

Answer:Yes, water indeed expands when it changes form from liquid to solid. And this is because water has a property called “hydrogen bonds”, and these bonds occur between each water molecule. But when water is in a liquid form these hydrogen bonds break more easily and occur less frequently. When the temperature drops the kinetic energy also drops, which in turn makes hydrogen bonds form more frequently. So the water molecules form a lattice, which is less dense than regular liquid water.
