Which statement describes the energy changes that occur when water in a tea kettle is heated on a stove that uses natural gas
A:Some of the chemical energy in the natural gas transforms into thermal energy, which heats the water. Then some of the thermal energy changes into sound energy when the water forms steam and the steam leaves the kettle.
B:Some of the electrical energy in the natural gas transforms into thermal energy, which causes the water to form steam. Then some of the thermal energy changes into sound energy and light energy when the steam leaves the kettle.

A book is sliding across a horizontal tabletop. As it slides, slows down. Which of the following statements best explains this situation?
There is a balanced force on the book caused by gravity.
There is no upward force acting on the book.
There is an unbalanced force on the book caused by friction.
There are no unbalanced forces acting on the book.
A book is sliding across a horizontal tabletop. As it slides, slows down. There is an unbalanced force on the book caused by friction.
What is friction ?The force preventing sliding against one another of solid surfaces, fluid layers, and material components is known as friction. There are several kinds of friction, The force that opposes the relative lateral motion of two solid surfaces in contact is known as dry friction.
When a stick is used to beat the carpet, a little amount of static friction occurs, holding the dust to the carpet. When we beat a carpet with a stick, the stick's external force forces the carpet to move away from the dust by overcoming friction.
A frictional force or an opposing force is produced when two rough surfaces come into contact with one another. This force can occasionally be transformed into heat.
Thus, option C is correct.
