Based on the kinetic molecular model, solids usually have higher densities compare two liquids. However, ice , a solid form of H2O floats on liquid water which means ice is less dense than water. What do you think is the reason for this phenomenon? What is the biological significance of this concept?
Use vapor pressure.
A student leaving campus for spring break wants to make sure the air in his dorm room has a high
water vapor pressure so that his plants are comfortable. The dorm room measures 3.41 mx 4.41 m x
3.90 m and the student places a pan containing 0.874 L of water in the room. Assume that the room is
airtight, that there is no water vapor in the air when he closes the door, and that the temperature
remains a constant 22 °C. The vapor pressure of water at 22 °C is 19.8 mm Hg.
(a) Calculate the pressure that the water vapor would exert if all of the liquid water evaporated.
mm Hg
(b) Will all of the water in the pan evaporate? [
1. Carbon dioxide gas has an initial pressure of 650 mmHg and an initial volume of 0.50 L. At constant
temperature and in a closed-system, what is the pressure (in atm) when the volume of the sample is
decreased to 125 mL?
2. Under constant pressure, a sample of hydrogen gas initially at 88.0 °C and 9.40 L is cooled until its
final volume is 2.50 L. What is its final temperature in the unit of Kelvin?
3. Given that 35.5 g of carbon monoxide are present in a container if volume 250 mL. What is the
pressure of the gas (in atm) if the temperature is 55 °C.
4. What volume is occupied by 15.5 g of argon gas at a pressure of 820 mmHg and a temperature of
50.0 °C? Would the volume be different if the sample were 15.5 g of chlorine gas (under identical
conditions)?
