At standard atmospheric pressure, the solid form of carbon dioxide called "dry ice" undergoes a phase change not to a liquid, but straight to a gas. This process is calledsublimation, and like other phase transitions, heat energy is required. In this case, it is the latent heat of sublimation, which for carbon dioxide is 573 kJ/kg at the sublimation temperature of ?78.5°C. If 160 g of dry ice is dropped into 0.50 L of water at room temperature (20°C), how much of the water will turn to ice by the time all the dry ice has sublimated? Note: When dry ice becomes a gas, the gas bubbles out of the system.
