Respuesta :

Answer:

  1. causing air molecules to vibrate
  2. air,liquids or solids
  3. At the north pole
  4. Heat energy
  5. conduction
  6. radiation
  7. Kinetic chemical energy
  8. in the bonds between atoms
  9. A nuclear reaction
  10. Electrons
  11. insulators
  12. conductors

Explanation:

when making sounds air molecules vibrates and these air molecules bump into one another causing sound to be produced.

The medium by which sound can be generated and transferred are air, liquids or solids

The sound would travel slowest at the north pole because the density of the areas

Another name for thermal energy is heat energy

The type of heat transfer that involve direct contact between two objects is conduction because it involves the transfer of heat between atoms which can be achieved by direct contact between elements containing the atoms

sunbathers warming up in the bright sun gets heat energy via Radiation from the sun

Kinetic chemical energy is released when bonds form in a chemical reaction because potential chemical energy exists between bonds of atoms

potential chemical energy is stored in the bonds between atoms

when chemical energy is released a nuclear reaction is formed

kinetic electrical energy is caused by the flow of electrons

materials that cannot carry electric energy are called insulators and they also inhibit the flow of electrical energy in them

Materials that can carry electric energy are called conductors

Multiple choices are 1. causing air molecules to vibrate; 2. air, liquids, or solids; 3. At the north pole; 4. Heat energy; 5.conduction; 6.radiation etc.

What are Electromagnetic waves?

When creating sounds air molecules vibrate and these air molecules bump into one another inducing sound to be produced. When The medium by which sound can be generated and also transferred are air, liquids, or solids Then, The sound would travel slowest at the north pole because of the density of the areas Now, Another name for thermal energy is heat energy.

When The kind of heat transfer that involves immediate contact between two things is conduction because it involves the transfer of heat between atoms which can be achieved by a direct connection between elements retaining the atoms. The sunbathers heating up in the bright sun get heat energy via Radiation from the sun.

When the Kinetic chemical energy is discharged when bonds form in a chemical reaction because potential chemical energy exists between bonds of atoms. When the potential chemical energy is stored in the bonds between atoms. when the chemical energy is released under a  nuclear reaction is formed.

When the kinetic electrical energy is caused by the flow of electrons. When materials that cannot carry electric energy are called insulators and they also inhibit the flow of electrical energy in them. Also, The Materials that can carry electric energy are called conductors.

   Multiple choice questions are:

  1. Causing air molecules to vibrate
  2. Air, liquids, or solids
  3. At the north pole
  4. Heat energy
  5. Conduction
  6. Radiation
  7. Kinetic chemical energy
  8. In the bonds between atoms
