What else can I help you with?
A substance will exist as a gas at ambient temperature and pressure?
A substance will exist as a gas at ambient temperature and pressure if its boiling point is below the ambient temperature and its vapor pressure exceeds the atmospheric pressure at that temperature.
Which condition will pressure altitude be equal to true altitude?
When standard atmospheric conditions exist.
Can carbon dioxide be a liquid?
Yes, carbon dioxide can exist as a liquid under certain conditions of temperature and pressure. At atmospheric pressure, it sublimes directly from a solid to a gas (dry ice). However, under high pressure and low temperature, it can exist as a liquid.
What phase is present at room temperature and normal atmospheric pressure?
At room temperature and normal atmospheric pressure, most substances exist in either the solid or liquid phase. Some exceptions include noble gases like helium and neon, which exist as gases at these conditions.
What is the importance of atmospheric pressure in earth?
IMPORTNCE OF ATMOSPHERIC PRESSURE It creates wind. It influences weather. Weather forecasting. Now i think all your doubts are clear.............................. By Sirjay Ambawat............
What are all states of matter for nitrogen?
Above 126 K (-147 C) nitrogen is always a gas, whatever the pressure. At atmospheric pressure, nitrogen liquefies at 77 K (-196 C) and solidifies at 63 K (-210 C)
At normal atmospheric pressure and a temperature of 0 and degC which phase(s) of H2O can exist?
At normal atmospheric pressure and a temperature of 0 degrees Celsius, water can exist in both solid and liquid phases. At 0 degrees Celsius, water can exist as ice (solid form) or liquid water, depending on the conditions.
Is nitrogen a compressed gas?
Nitrogen can exist as a compressed gas when placed under pressure in a container. At room temperature and normal atmospheric pressure, nitrogen is a colorless and odorless gas.
In which state of matter do most elements exist?
Most elements exist in the state of matter known as solids at room temperature and pressure. Some elements can also exist as liquids or gases depending on the conditions.
Why does the Earth support life so well?
The honest answer is "just lucky", but temperature and atmospheric pressure such that water can exist in liquid form is critical.
Why are you not crushed by atmosperic pressure?
Because your structure has evolved in order to withstand atmospheric pressure. A creature that could not survive atmospheric pressures would not be able to survive, and therefore would not be able to produce offspring. All of the body's tissues contain dissolved air (nitrogen & oxygen) at pressure equilibrium with the atmosphere. In effect the body "pushes back" against atmospheric pressure, just as ocean creatures withstand crushing water pressure by mostly consisting of water.
What is the unit of measuring atmospheric pressure?
The unit of measuring atmospheric pressure is called a "pascal" (Pa), which is equivalent to one newton of force applied over one square meter. Another common unit used is the "bar", where 1 bar is equal to 100,000 pascals.
