What happened before kilauea eruption?
Before the Kilauea eruption in 2018, there were increased seismic activity and ground deformation around the volcano, indicating that magma was moving underground. This period of unrest led to lava flows and fissures opening up in the lower East Rift Zone of the volcano, eventually culminating in the eruption.
How water is evaporated at a lower temperature under vacuum conditions?
Under vacuum conditions, the pressure is lower, which reduces the boiling point of water. This allows water to evaporate at a lower temperature than under normal atmospheric conditions. The lower pressure decreases the need for high temperatures to overcome atmospheric pressure and facilitate evaporation.
What is atmospheric density a function of?
Atmospheric density is a function of altitude, temperature, and pressure. As altitude increases, density decreases due to the lower pressure and temperature in the upper atmosphere. Conversely, density increases at lower altitudes where pressure and temperature are higher.
What factors determine whether a volcano has a violent or quiet eruption?
A volcano erupts when enough pressure builds up inside of it to unplug it's crater. The stronger the plug, the more force is needed to expel it, which results in a more violent eruption. Also, the stickiness of the lava is a factor. The more sticky the lava, the stronger the eruption.
State and explain how the boiling point of water will change if the atmospheric pressure falls?
Water boils when its internal pressure reaches that of the atmospheric pressure. Therefor, if one lowers the atmospheric pressure, the water would boil at a lower temperature (in fact, one can make water boil at room temperature by dramatically lowering the atmospheric pressure).

Why is it different at 5000 feet to boil water?
The atmospheric pressure is lower. When you are boiling the water, the water's vapour saturation pressure is able to match the atmospheric pressure faster therefore it boils faster and at a lower temperature.
What are the standard atmospheric conditions for water to boil at 212 degrees Fahrenheit?
Water boils at 212°F (100°C) at standard atmospheric pressure of 1 atm or 14.7 psi. At higher elevations, where atmospheric pressure is lower, water will boil at a lower temperature.
Does water boil the same at sea level as it does at higher elevations?
Water boils at a lower temperature at higher elevations because the atmospheric pressure is lower. At higher elevations, there is less air pressing down on the water, so it requires less energy to reach the boiling point.
Why does water boil at a lower temperature on a mountain than sea level?
Water boils at a lower temperature at higher altitudes because water boils when the vapor pressure of the heated water matches the pressure of the atmosphere pushing downward. Since there is a higher atmospheric pressure at sea level than in say a mountain, the temperature needed to boil water decreases.
What is lower fixed point?
upper fixed point is a temperature of stem from water boiling and standards atmospheric pressure lower fixed point is the temperature of pure melting ice.

Why would water boil at less than 100 degrees on top of a mountain?
The boiling point of any liquid is the temperature at which its vapor pressure becomes equal to the atmospheric pressure. So if the atmospheric pressure is lower, it will take a lower temperature to make the vapor pressure equal to that of atmospheric pressure. At hill-stations, the air is generally thinner due to the altitude and the atmospheric pressure is also lower. Here, it requires less than 100oC temperature to reach the point where the vapor pressure of water reaches that of air. So, water boils below 100oC at hill stations.
