Gas
-20 degrees Celsius = -4 degrees Fahrenheit.
20 degrees Celsius = 293.15 kelvins
20 degrees Celsius = 68 degrees Fahrenheit.
20 degrees Fahrenheit = -6.6 degrees Celsius.
Hydrogen is in a gaseous state at 20 degrees Celsius.
Hydrogen is a gas at 20 degrees, Fahrenheit and Celsius, but it you are talking Kelvin, then it is a liquid.
No, hydrogen is a gas at room temperature and pressure, including at 20 degrees Celsius. At much colder temperatures (below -252.87 degrees Celsius), hydrogen can be in a solid state.
At 20 degrees Celsius, nitrogen is in a gaseous state as it has a boiling point of -196 degrees Celsius and a melting point of -210 degrees Celsius.
At 20 degrees Celsius, copper is in its solid state. Copper has a melting point of 1,085 degrees Celsius, so at 20 degrees Celsius, it remains a solid metal.
At 20 degrees Celsius, aluminum is in its solid state. Aluminum has a melting point of 660.3 degrees Celsius, so at 20 degrees Celsius it remains solid.
Gold is a solid state at 20 degrees Celsius. Gold has a melting point of 1,064 degrees Celsius and a boiling point of 2,807 degrees Celsius, so at 20 degrees Celsius it would be in its solid phase.
At 20 degrees Celsius, wax is typically in a solid state.
At 20 degrees Celsius, copper is in a solid state. Copper melts at 1,085 degrees Celsius, so at 20 degrees Celsius, it remains solid.
Argon is typically a gas at room temperature (20 degrees Celsius). It has a boiling point of -185.7 degrees Celsius, so it would be a gas at 20 degrees Celsius.
Gold would be in solid state at 20 degrees Celsius because its melting point is 1064 degrees Celsius.
Argon is a gas at 20 degrees Celsius. Its boiling point is -185.7 degrees Celsius, so it remains in the gaseous state at 20 degrees Celsius.
