How does water vapor cause global warming?
Increased water vapor content in the atmosphere is referred to as a feedback process. Warmer air is able to hold more moisture. The increase in water vapour in the atmosphere, because water vapour is an effective greenhouse gas, thus contributes to even more warming: it enhances the greenhouse effect.
What is the chemical composition of water vapor?
Water vapor
| Water vapor (H2O) | |
|---|---|
| Molecular formula | H2O |
| Molar mass | 18.01528(33) g/mol |
| Melting point | 0.00 °C (273.15 K) |
| Boiling point | 99.98 °C (373.13 K) |
What is the chemical reaction of water vapor?
Hydrogen gas and oxygen gas react to produce water vapor. The hydrogen gas and the oxygen gas react at a volume ratio of 2: 1 to generate 2 volumes of water vapor. When the gas reacts at a constant temperature and pressure and a new gas is produced, there is always a simple integer ratio between each gas’s volumes.
What is the chemical equation for global warming?
Source
| Greenhouse gas | Chemical formula | |
|---|---|---|
| Carbon Dioxide | CO2 | 100* |
| Methane | CH4 | 12 |
| Nitrous Oxide | N2O | 121 |
| Chlorofluorocarbon-12 (CFC-12) | CCl2F2 | 100 |
How do water Vapours and carbon dioxide contribute to the phenomenon of global warming?
Carbon dioxide and water vapour are considered greenhouse gases. This statement means that these compounds adsorb much heat due to high heat capacity. As the temperature increases, more water evaporates from the water bodies surfaces. As a result, the average temperature increases leading to global warming.
Is water vapour a gas or liquid?
Water vapour is water in gaseous instead of liquid form. It can be formed either through a process of evaporation or sublimation. Unlike clouds, fog, or mist which are simply suspended particles of liquid water in the air, water vapour itself cannot be seen because it is in gaseous form.
Is water vapor a chemical?
Water vapor still has the same chemical formula as typical water – H2O – but the water molecules in vapor interact less with one another and are not as structured as they are in water and ice. Whether or not water will be in liquid or gas form is dependent on pressure, temperature, and relative humidity.
Is water Vapour a compound or element?
Water vapor can exist with or without the presence of air. Since water is a compound and water vapor is just its gaseous form, then water vapor is also a compound.
What are water vapor molecules?
Water vapor is water in the gaseous state and is invisible to the human eye. Water will turn into vapor, or evaporate, in order to reach equilibrium. Water vapor is invisible, but as it rises and the temperature decreases, some of the molecules condense into liquid water.
What are the hazardous chemicals that can cause global warming?
But methane, nitrous oxide, hydrofluorocarbons (HFCs), chlorofluorocarbons (CFCs) and perfluorocarbons (PFCs) are also important agents of global warming — some of them are actually much more potent than CO2 and they stick around for hundreds to thousands of years longer.
