Trying to move a large object such as a furniture piece across carpet.
Answer: Temperature is the average kinetic energy of the molecules (how hot or cold something feels). Heat energy is the energy created y the motion of the molecules in an object. Heat flows from hot body to cold body. Temperature rises when heated and falls down when an object is cooled down.
There are three main scales commonly used in the world today to measure temperature: the Fahrenheit (°F) scale, the Celsius (°C) scale, and the Kelvin (K) scale. Each of these scales uses a different set of divisions based on different reference points, as described in detail below.
Explanation:
Refraction is the change in direction of waves that occurs when waves travel from one medium to another. It is always accompanied by a wavelength and speed of change. Diffraction is the bending of waves around obstacles and openings.
