Answer

36. C. Destructive ### 37. C. Diffraction ### 38. Echo ### 39. Specific Heat Capacity ### 40. Heat Explanation 1. Identify Interference Type Two identical waves moving in opposite directions and out of phase result in **Destructive interference**. 2. Determine Sound Phenomenon Hearing sound through an open doorway without seeing the source is due to **Diffraction**. 3. Define Reflection of Sound The reflection of sound is **Echo**. 4. Define Specific Heat Capacity The quantity of heat needed to raise the temperature of 1 kg of a substance through 1^\circ C or 1 K is **Specific Heat Capacity**. 5. Define Energy Flow The energy that flows from high temperature to low temperature is **Heat**.
