The remaining compounds in the gas could be just. about anything, depending on the climate and the. garbage profile. The exact composition of landfill. gas is unique to each location. Monitoring is. important if specific trace compounds are to be. identified.
What is the first step of the dissolving process out of these choices ? 1. the molecules of the solvent pull the molecules of the solute into solution 2. the molecules of the solute pull the molecules of the solvent into solution 3. the moving molecules of the solvent spread the molecules of the solute equally...
Introduce the process of condensation. If students do not know what the process of condensation is, you can tell them it is the opposite of evaporation. In evaporation, a liquid (like water) changes state to become a gas (water vapor). In condensation, a gas (like water vapor) changes state to become a liquid (water). Explain that as water molecules in the air cool and slow down, their attractions overcome their speed and they join together, forming liquid water. This is the process of condensation.
