Term1/13

Vaporization is the conversion of a liquid to a gas or vapor when the liquid is

Definition1/13

AT its boiling point.

Term1/13

Boiling liquid maintains a constant temperature because

Definition1/13

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.

Term1/13

A box with a volume of 22.4 L contains 1.0 mol nitrogen and 2.0 mol hydrogen at 0à Celsius Which of the following statements is true

Definition1/13

the partial pressure of N2 is 101kPa

Term1/13

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

Definition1/13

If the sample is at 100 0C, at standard pressure, no supplementary heating is necessary.

Term1/13

Pressure is used to increase the volume of gas

Definition1/13

Pressure is used to increase the volume of gas in Boyle's law.

What is true about a solid and liquid

Definition1/13

they are both states of matter

Term1/13

Is the change of state of a substance from solid to vapor without passing through the liquid state.

Definition1/13

The change of state is called sublimation.
