The temperature at which the vapor pressure of a liquid has an external pressure of 1 ATM is the
The point at which the vapor pressures of a substance in gas liquid and solid form are in equilibrium is called
The heat needed to boil away one gram of a liquid at its boiling point is
Vaporization is the conversion of a liquid to a gas or vapor when the liquid is
Boiling liquid maintains a constant temperature because
The boiling point temperature remains constant because liquids
evaporate at this point. If the temperature drops the liquid will
no longer boil. At a higher temperature the vapor becomes hotter,
not the liquid.
A sample of H2O with a mass of 46.0 grams has a temperature of 100.0C How many joules of energy are necessary to boil the water
If the sample is at 100 0C, at standard pressure, no
supplementary heating is necessary.
Calculate the energy released when a 28.9 gram piece of copper is cooled from its melting point of 1083 àC to 25.0 àC The specific heat of copper is 385 Jg àC
Does evaporation rais the tempeature of a liquid
Evaporation does not raise the temperature of a liquid,
evaporation happens because of the increasing temperature of that
liquid.
How many joules of energy are necessary to heat a sample of water with a mass of 46.0 grams for 0.0
46 calories (or 192, 464 joules) for each Celsius degree.
How much energy is needed to melt 4.24 grams of Pd
The temperature at which the vapor pressure of a liquid is equal to the exernal pressure is the
The temperature at which the vapor pressure of a liquid is equal
to the external pressure is the boiling point.
Is it true that above the temperature no amount of pressure will casue a gas to liquefy
The critical temperature of a gas is the temperature at or above
which no amount of pressure, however great, will cause the gas to
liquefy.
