What is gravitational potential energy

Gravitational potential energy is the potential energy an object has due to its position in a gravitational field. The higher an object is the greater its gravitational potential. When it falls the gravitational potential becomes kinetic energy.

Energy stored in height differences ~APEX

What is chemical potential energy

It is another form of potential stored in food, batteries, and fuel.

How do solid change their shape

Solids change their shapes in many ways. Solids will melt if they are in hot temperatures, and this changes their shape.

Which of the following is the best example of an open system

an anthill

What does the law of conservation of energy imply

energy can neither be created nor we destroy

That energy can only be converted between different forms ~Apex

What did John Dalton publish

An early theory describing properties of atoms

What law states that matter can never be created or destroyed

The law of conservation of matter

Which of the following has mass and takes up space

Anything that lives except air, light, sound.

What does the law of conservation of matter show

That the total number of atoms in matter will never change

Answer2:

As I learned it:

Matter can neither be created nor destroyed, only changed in form.

This is/was Newtonian physics. Einstein showed that in nuclear events matter can be changed to energy. And, in general relativity even more complex change can occur.

Which of the following is a covalent bond

No following, but look for the nonmetal to nonmetal bond.

Which of the following is an example of a phase change from liquid to solid

Water freezing into ice is an example of a phase change from liquid to solid.

How does gravity depend on an object's mass

yes unless its kavanha

What is the capacity to do work known as apex

Energy

-Apex

What takes up space in a atom

The most space is vacuum.

Which phase of matter is the least common on earth

Liquids

which of the following contains matter

Atoms

which of the following properties describes plasma

it can change shape and volume
