In designing a house, the best place for a heater is? Explain your answer
The floor. Heat rises, so having the heater near the floor will allow more of the room to heat.
500
explain the difference between reflection, refraction and absorption.
reflection is light bouncing off a shiny surface, refraction is the bending of light as it passes through a medium and absorption occurs when light is absorbed by the surface and converted to heat.
