Document Summary
False: solid material heating up faster than water, water holds more heat. --water and phase transitions: when you add heat to water, you increase temperature. Lower: transition from ice to water and water to vapor, adding heat, but no change in temperature is occurring sometimes. False: permanent hydrogen bond in the ice to a temporary bond in solution. Sensible heat: add heat but no change in temperature is called latent heat. Latent heat of fusion- energy required to break the permanent hydrogen bonds. Latent heat of vaporization- energy needed to break temporary hydrogen bonds. Latent heat of fusion: alcohol boils faster than water. --latent heat of fusion and polar ice: exothermic reaction- forming hydrogen bonds releases energy. In water, both light and sound travel like waves: wave crests bend almost 90 degrees as they move around the shallow part of the ocean, bending of the wave is called refraction.
