which of the following statements is NOT true according to the kinetic theory
only particles of matter in the gaseous state are in constant motion
which of the following statements is NOT true about the movement of particles in a gas
particles usually travel uninterrupted indefinitely
how does the atmospheric pressure at altitudes below sea level compare with the atmospheric pressure at sea level
below sea level its higher
what causes gas pressure in a container such as a helium balloon
simutaneous collisions of fast moving particles in container
what happens to the average kinetic energy of the particles in a sample of matter as the temp of the sample is increased
average kinetic energy increases
what happens to the range of energies of the particles in matter when the temp is increased
the range of energies becomes broader
the average kinetic energy of the particles of a substance__
is directly poportional to the temp of the substance
when a gas is heated__
of the absorbed energy's converted to potential energy and same converted to kinetic energy
Consider an iron cube and an aluminum cube. If the two cubes were at the same temperature, how would the average kinetic energy of the particles in iron compare with the average kinetic energy of the particles in aluminum?
There would be no difference in the average kinetic energies.
why does a liquid's rate of evaporation increase when the liquid is heated
more molecules have enough energy to overcome attract forces holding them in the liquid
In a dynamic equilibrium between the liquid state and the gas state, what is true about the rate of evaporation?
it is equal to the rate of condensation
If a liquid is sealed in a container and kept at constant temperature, how does its vapor pressure change
it increases at first, then remains constant
If energy is added to a boiling liquid what happens to the temperature of the liquid
It does not change
water could be made to boil at 105 degrees Celsius instead of 100 degrees Celsius by
increasing the External pressure
When the external pressure is 505 kPa what is the vapor pressure of water at its boiling point?
The normal boiling point of chloroform, which has a higher vapor pressure than water at 100*C is
Lower than the normal boiling point of water
which of the following best describes the motion of the particles in a piece of steel
all are moving
Compared to melting points of ionic compounds, the melting points of molecular solids tend to be
the smallest group of particles in a crystal that retains the shape of the crystal is called the
How are conditions of pressure and temp, at which two phases coexist in equilibrium, shown on a phase diagram
by a line separating the phases
