There, and in Alaska, Hawaii, and elsewhere, this model is being extended to. primary and in some cases secondary school. And in. California, younger adults have become language. apprentices to older adult speakers in communities. where only a few older speakers are still living. A growing number of conferences, workshops, and pub-. lications now offer support for individuals, schools, and. communities trying to preserve languages.
Because the liquid is volatile, it can easily be converted to a gas. substance is in the gas phase, you can measure its volume, pressure, and temperature. then use the ideal gas law to calculate the number of moles of the substance. the number of moles of the gas to calculate molar mass. substance as it condenses.
3) That's right. Some, maybe all, of the liquid will evaporate into gas, filling the empty space. Now if all the liquid evaporates, we just have a box of gas. That's not what we want. So let's suppose that only some of the liquid evaporated and that there are both the liquid state and the gas state present in the box. The gas that is above the liquid is called its vapor and it creates a pressure called vapor pressure. What I mean is this: suppose you put a gas-pressure measuring device into the gas and never touched the liquid.
