To calculate the number of moles of ethanol in vapor at 70 degrees Fahrenheit, you would need to know the volume of the vapor and the pressure it is under. Using the ideal gas law equation (PV = nRT), where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature in Kelvin, you can solve for n.

How fast does ice melt at 450 degrees Fahrenheit?
Ice melts at 32 degrees Fahrenheit, so at 450 degrees Fahrenheit, the ice would rapidly melt and eventually boil away as water vapor. The exact speed of melting would depend on the environment, such as air flow and heat source.
What degree does water boil and melt at?
Water boils when the temperature gets to 212 degrees Fahrenheit or 100 degrees celsius. Water does not melt. It changes into a vapor-like fog and disappears into a gas.
How hot would temperatures have to be for all Earth's water to evaporate and remain vapor?
For all of Earth's water to evaporate and remain as vapor, temperatures would need to exceed 100 degrees Celsius (212 degrees Fahrenheit) to reach the boiling point of water. Once water evaporates into vapor, it would continue to expand and dissipate into the atmosphere.
Why does a hurricane weaken cool ocean waters?
In simple terms, hurricanes are fueled by water vapor. More vapor evaporates from warm water than from cold water. If water temperatures are less than about 80 degrees Fahrenheit, then there will not be enough water vapor to sustain a hurricane.
What energy is needed for water to turn into water vapour?
As soon as the temperature drops below the dew point, water will condense from water vapor.
Is ethanol a solid liquid or gas at 1000 degrees?
Ethanol would be a gas (vapor) at 1000 degrees Farenheit, Centigrade or Absolute (Kelvin).
What is the temperature at which water boils on the Fahrenheit?
"Turning to vapor" is a description of boiling. At normal conditions, water boils at 212oF.
What is the vapor pressure of ethanol at 14 degrees celsius?
The vapor pressure of ethanol at 14 degrees Celsius is approximately 63.1 mmHg.
What is the freezing point of water vapor?
The freezing point of water vapor is 0 degrees Celsius or 32 degrees Fahrenheit. At this temperature, water vapor turns into solid ice.
How much energy is released when 496 g of ethanol 46.0 g mol vapor condenses The heat of vaporization of ethanol is 38.6 kJ mol?
To calculate the energy released when 496 g of ethanol vapor condenses, first convert the mass of ethanol to moles. Then, use the heat of vaporization value to determine the energy released per mole of ethanol. Finally, multiply the energy released per mole by the number of moles in 496 g to find the total energy released.
How much degrees Fahrenheit does water vapor?
It is generally 212 deg F or higher.
What happens when water reaches 212 degrees Fahrenheit?
Water reaches its boiling point of 212 degrees Fahrenheit at standard atmospheric pressure. At this temperature water transitions from liquid to vapor, forming steam.
What is the vaporization point or paraffin wax?
Paraffin wax begins to melt at temperatures above 99 degrees Fahrenheit. It begins to boil and produce vapor at approximately 698 degrees Fahrenheit.
How many btu are required to change 10 pounds of r-134a from liquid at 20 degrees Fahrenheit to vapor at 30 degrees Fahrenheit with 22.89 psig?
1.5million
Does water melt?
No, water does not melt. It freezes at 0 degrees Celsius (32 degrees Fahrenheit) and becomes ice, and it evaporates at 100 degrees Celsius (212 degrees Fahrenheit) to become water vapor.
What is the condesation point of water?
The condensation point of water is 100 degrees Celsius (212 degrees Fahrenheit) at standard atmospheric pressure. At this temperature, water vapor transitions into liquid water.
How much degrees Fahrenheit does water turn into water vapor?
Water turns into water vapor at 212 degrees Fahrenheit at standard atmospheric pressure.
