B-C Does temperature change significantly during a phase change No Does the surrounding air warm or cool as clouds form warms Explain why sweating cools you down As the sweat evaporates the sweat gains heat from your body Phase change when water vapor becomes water condensation Which phase has the most energy Gas Can you see water vapor no What are the 2 examples of vaporization Evaporation & boiling What is the difference between evaporation and boiling Boiling occurs throughout and evaporation only occurs at the surface What is the formula of relative humidity Humidity divided by capacity times 100 Can warm or cold air hold more water vapor Warm As the air warms up does the humidity have to change No (humidity is not affected by temperature) What time of day has the highest relative humidity dawn If the temperature decrease and the humidity remains constant does the relative humidity go up or down up Solid which is needed for condensation Condensation nuclei Do clouds form or evaporate as warm air rises form What are we looking at when we see our breathe ? water Was the air saturated when the sweat formed on the can? yes Explain why the orange does not get ruined ? As the water freezes it releases latent heat into the orange CanRelative the relative humidity humidity NO ever be 100%
