Across
- 1. the resistance of a substance such as water to changes in temperatures
- 6. the ability of ice to act as a barrier that slows down the loss of heat from the water beneath it
- 7. The attraction between molecules of different substances, such as water molecules sticking to a glass surface
- 10. The tightness on the surface of water caused by the cohesive forces between water molecules, making the surface act like a stretched elastic sheet
- 11. a substance that can dissolve a wide variety of solutes water is known as the universal solvent because it can dissolve more substances than any other liquid
- 13. a homogeneous mixture composed of two or more substances
- 16. The amount of heat energy required to raise the temperature of a substance by 1c waters high specific heat allows it to stabilize environmental temperatures
Down
- 2. the amount of heat energy required to raise the temperatures
- 3. A weak bond between two molecules, where a hydrogen atom in one molecule is attracted to an electronegative atom in another, common in water molecules
- 4. the mass of a substance per unit volume water is unique because its solid form is less dense than its liquid form allowing ice to float
- 5. the ability of water to flow in narrow spaces against gravity
- 8. the measure of a fluids resistance to flow
- 9. The attraction between molecules of the same substance, such as water molecules sticking together
- 12. a substance that dissolved in a solvent
- 14. The characteristic of a molecule having distinct positive and negative ends, leading to the formation of hydrogen bonds in water
- 15. a measure of the acidity or basicity of a solution pure water has pH of 7
