At normal pressure, none of them. At greatly reduced pressure, any of them- depending on the pressure.
The new temperature outside would be 4 degrees. -2 + 6 = 4.
Increased pressure on the inside, or decreased pressure on the outside.
34 degrees
an example of air pressure would be 45% of water vapor outside.
The pressure exerted on the outside of the can would be 50 Pa (P = F/A).
The pressure would decrease to zero because a gas at 0 degrees Celsius is frozen, and frozen gas does not exert any pressure due to lack of molecular motion.
To convert Celsius to Kelvin, add 273.15 to the Celsius temperature. Therefore, if it is 65 degrees Celsius outside, it would be 338.15 Kelvin.
It would be 0° C outside your coat, and 20° C or more inside it.
The boiling point of water at standard pressure is 100 degrees Celsius or 212 degrees Fahrenheit.
The pressure is much less outside the plane and opening the window would cause a rapid movement from high pressure inside to low pressure outside and suck things out of the plane window.
At 1000 degrees, methane would be in a gaseous state. Methane typically exists as a gas at room temperature and pressure, so at 1000 degrees it would remain a gas.
