Experiment 3: Surface Tension of n-Butanol and
In this experiment, surface tension of n-Butanol and amount adsorbed were determined.
This was done using a capillary tub

The amount of heat required to raise the
temperature of one gram of a substance by
one degree Celsius is called
1) heat of fusion
2) specific heat capacity
3) vapor pressure
4) heat of vaporization
Which temperature is
Unit 5: Gases
I. Pressure and Manometers
Gas particles move in straight line paths. As they collide, they create a force, pressure.
Pressure = Force / Area
Standard Atmospheric Pressure = 14.7 psi
(at sea level)
= 101325 Pa
= 1 atm
Terms for you to learn that will make this unit understandable:
Energy (E) the ability to do work or produce heat ; the sum of all potential and kinetic energy in
a system is known as the internal energy of the system
1. Which graph shows the pressure-temperature
relationship expected for an ideal gas?
2. Under which conditions does a real gas behave most like
an ideal gas?
1) at low temperatures and high pressures
2) at low temperatures and low pressures

The stoppered tubes below, labeled A
through D, each contain a different gas.
When the tubes are unstoppered at the same
time and are under the same conditions of
temperature and pressure, from which tube
will gas diffuse at
