Across
- 2. Material added into ceilings and between the walls of a house to reduce heat transfer.
- 3. Heat transfer as a wave, which can even travel through the vacuum of space.
- 4. Energy that travels as vibrating waves and can be heard by our ears as sound.
- 5. Heat transfer between two objects in contact. Heat transfers from the hotter object to the cooler one, until they are both the same temperature.
