It is a gas.
Yes, it is.
20 degrees Celsius = 68 degrees Fahrenheit Formula: [°F] = [°C] × 1.8 + 32

20°C
The temperature difference between -20°C and 40°C can be calculated by subtracting the lower temperature from the higher one. This gives us 40°C - (-20°C) = 40°C + 20°C = 60°C. Therefore, there are 60 degrees between -20°C and 40°C.
At a temperature of 20 degrees C (or F, for that matter) oxygen is a gas.
Iodine is a solid at 20 degrees Celsius.
It is a gas.
Neon has a boiling point of -246.1 degrees Celsius (-411 degrees Fahrenheit). At this temperature, neon transitions from a liquid state to a gas state.
Barium is a solid at 20 degrees Celsius.
Neon freezes at about -416.2 degrees Fahrenheit. -- To be more specific, Neon turns liquid at -245.92°C (-410.66°F) and solid at -248.6°C (-415.5°F).
Gaseous state. The boiling point of radon is -71 degrees C. So at 20 degrees C, it is above the boiling point and is a gas at this temperature.
Plutonium is a solid at 20 degrees Celsius. It has a melting point of 639.4 degrees Celsius and a boiling point of 3228 degrees Celsius, so at 20 degrees it would be in a solid state.
The melting point of neon is -248.67 degrees Celsius.
