What do you call the temperature at which water vapor occurs because of cooling?
I believe you mean the temperature at which water vapor condenses due to cooling. This is the dew point temperature.
Smooth glassy rock that is formed when lava cools?
Obsidian
Why NH3 is used in refrigerator?
Anhydrous ammonia is used in Refrigerators. Anhydrous ammonia is a clear liquid that boils at a temperature of -28°F. In refrigeration systems, the liquid is stored in closed containers under pressure. When the pressure is released, the liquid evaporates rapidly, generally forming an invisible vapor or gas. For changing its state (form liquid to gas), the bonds need kinetic energy. The (heat) energy is taken from its environment (inside the refrigerator), which changes in kinetic energy. Due to which, evaporation occurs. The rapid evaporation causes the temperature of the liquid to drop until it reaches the normal boiling point of -28°F, a similar effect occurs when water evaporates off the skin, thus cooling it. This is why ammonia is used in refrigeration systems
The formation of igneous rocks is powered by?
the cooling and solidification of molten magma or lava. This process occurs either underneath the Earth's surface, resulting in intrusive igneous rocks, or on the surface, leading to extrusive igneous rocks. The rate of cooling determines the texture and crystal size of the rock, with slower cooling allowing for larger crystals to form.
What is the rate of cooling as you increase in elevation?
The rate at which adiabatic cooling occurs with increasing altitude for wet air (air containing clouds or other visible forms of moisture) is called the wet adiabatic lapse rate, the moist adiabatic lapse rate, or the saturated adiabatic lapse rate.
What is adiabatic cooling?
Adiabatic cooling is cooling that occurs without removing any energy from the system. It often occurs when a gas is decompressed. Adiabatic heating and cooling play an important role in weather.
What occurs due to repeated heating and cooling of air?

Oil foaming ususally occurs in what area of a refrigeration system?
I'm in the process studying for my epa test and this is one of the questions and their answer is foaming occurs in the compressor.
How does surface area affect the rate of cooling of soup?
Increased surface area increases cooling. Cooling occurs by convection of air above the soup and water vapour loss.
What does global cooling do to the earth?
It cools it somewhat. Global cooling occurs after a volcanic eruption when clouds of dust remain in the sky for several days reflecting the sun's rays. This results in a cooling of the atmosphere.
What do you call the temperature at which water vapor occurs because of cooling?
I believe you mean the temperature at which water vapor condenses due to cooling. This is the dew point temperature.
Are the windows malfunctioning when condensation occurs on them?
no its just air cooling around you which forms water vapour on the window
When air rises does it expand and cool adiabatically?
Yes. Adiabatic cooling occurs when there is a change in only pressure.
What is adiabatic rate?
the rate of cooling that occurs when dry air rises without gain or loss of heat
How are crystallization and cooling magma related?
Crystallization and cooling magma are related in the sense that cooling and crystallization occurs simultaneously. As the magma cools it crystallizes, the faster the rate of cooling the quicker crystals would develop and the slower the cooling the larger the crystals in other cases when the magma cool so rapidly crystal development may not be so prominent.
What is dry adiabatic rate?
the rate of cooling that occurs when dry air rises without gain or loss of heat
What reaction occurs when rubbing alcohol is placed on the arm?
The cooling effect of alcohol on the skin is the result of?
