Which statement is correct about the law of conservation of energy

energy is created when water freezes.

energy is destroyed when sugar is burned.

energy stays inside molecules permanently.

energy is transferred when atoms are rearranged

The law of conservation of energy is energy isn't created or destroyed

A and B are wrong because there is creation or destruction of energy

C is wrong because energy can be transferred (think touching a hot stove with your finger.  heat is transferred from the stove to your finger OUCH!)

D is correct because the energy is still there, but in a different form

According to the law of conservation of energy, it states that energy can never be created and nor be destroyed. It can only transfer from one place to another.

There are different types of energy. The energy is as follows:-  

Heat energy Wind energy Light energy

The energy which is formed by the heat is called thermal energy.

According to the question, the correct option is C. Energy stays inside molecules permanently.

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
