Work on this in class on Monday and Tuesday.  If you need more time complete it for homework and hand it in on Wednesday.

Part 1: Relative humidity Reading: you do not need make a graph, just answer these questions
1. What is a hygrometer? How could you make one?
2. What is the change in the state of matter during evaporation?
3. Can a gas evaporate?
4. Use the hygrometer and the wet/dry table to find the humidity.What is the humidity in the room?

 Part 2: State of matter change of water graph:Use the graph in the back of the packet to answer the following questions.
1. What state of matter is water most likely to be in?
2. At 20 C, what states of matter can water be?
3. At 40 C would you more likely find water as a gas or a solid?
4. At a given temperature what can determine the state of matter of water?

Part 3: Relative Humidity Website  link about relative humidity.
1. Can the dew point ever be higher than the temperature?
2. How does changing the outdoor temperature impact the dew point?
3. How does changing the dew point change the relative humidity?
4. How does the indoor relative humidity compare to the outdoor relative humidity?
