Graphite is a solid at 20 0C.
Carbon dioxide is a gas at 10 degrees Celsius, as its boiling point is -78.5 degrees Celsius.
At negative 150 degrees Celsius, carbon would be in a solid state.
At -100 degrees Celsius, carbon dioxide would be in solid form, commonly known as dry ice.
At 1500 degrees Celsius, carbon exists primarily in the form of graphite, which is its stable allotrope under high temperatures and pressures. However, at such high temperatures, carbon can also undergo sublimation, transitioning directly from solid to gas. Additionally, in the presence of oxygen, carbon can react to form carbon dioxide (CO₂) or carbon monoxide (CO). The specific state can depend on the surrounding environment and pressure conditions.
Nitrogen is a gas at 25 degrees Celsius, while carbon dioxide can exist as a gas or a solid (dry ice) at this temperature.
25 deg. Celsius is about "room temperature," and assuming normal pressure (1atm) carbon dioxide is a gas.
25 deg. Celsius is about "room temperature," and assuming normal pressure (1atm) carbon dioxide is a gas.
At 20 degrees Celsius and 25 ATM pressure, carbon dioxide would be in a supercritical state, exhibiting properties of both a gas and a liquid.
At 20 degrees Celsius, carbon dioxide (CO2) is a gas. Under standard atmospheric pressure, it remains in a gaseous state at this temperature. Carbon dioxide can exist as a solid (dry ice) at temperatures below -78.5 degrees Celsius, and as a liquid only under high pressure, which is not the case at 20 degrees Celsius.
At 30 degrees Celsius, bromine is in a liquid state. Bromine has a melting point of -7.2 degrees Celsius and a boiling point of 58.8 degrees Celsius, so at 30 degrees Celsius it would be in a liquid state.
At 200 degrees Celsius, mercury is in a liquid state as its melting point is -38.83 degrees Celsius and boiling point is 356.73 degrees Celsius.
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.
