Use a Diagram, illustrate and fully explain why water is a “special case.” Include 2 ways this is useful to chemists (and in every day life).

What is this? Include the relationship between IMFs & E↓k

Explain why you feel colder faster on a hot, windy day than on a hot day with no wind?

Why does a pot without a lid take longer to boil than a pot with a lid on? be careful how you use the words “closed container” if you think it necessary to do so.

What is a dynamic equilibrium? You may use words or a picture to explain.

Calculate the vapor pressure in kPa of the gas in this open ended manometer, held at sea level (standard conditions)

120. kPa = Pgas

24\.0g of solid iron at 90.21°C is dropped in 99mL of water at 25.0°C. The final temperature of the system is 23.21256°C. Find the specific heat capacity of the iron.

C = 0.46 J/ g°C
