This download is my science worksheet. It's about different types of energy in a situation, like examples. btw this is 7th grade
scoray [572]

All types of energy can be resumed into two basic types of energy which include kinetic energy and potential energy.

<h3>What is kinetic energy?</h3>

Energy is the ability to perform a given work. Kinetic energy is energy in movement, whereas potential energy is stored energy.

For example, plant photosynthesis makes reference to chemical energy (potential energy), popcorn makes reference to thermal energy, etc.

In conclusion, all types of energy can be resumed into two basic types of energy which include kinetic energy and potential energy.

Molecules that have the same chemical formula (same numbers of each atom) but different three-dimensional shapes are called ____
Sveta_85 [38]

Answer:

            Molecules that have the same chemical formula (same numbers of each atom) but different three-dimensional shapes are called <u>Stereoisomers</u>.

Explanation:

                   Stereoisomerism is a phenomenon in which molecules have same molecular formula but have different arrangement of atoms or group of atoms in space. It is further classified as;

                      i) Geometrical Isomerism:

                                                                In this class of isomerism the groups or atoms about the double bond occupies different region in space. It is also called as <em>cis-trans </em>isomerism.

                      ii) Optical Isomerism:

                                                          In this class the molecules having same molecular formula differ in their interaction towards plane polarized light.
