Chlorine is a gas at 15 oC.
At 100 degrees Celsius, chlorine is in a gaseous state. Chlorine is a diatomic molecule with the chemical formula Cl2. At room temperature and pressure, chlorine exists as a greenish-yellow gas. As the temperature increases to 100 degrees Celsius, the kinetic energy of the chlorine molecules increases, causing them to move more rapidly and transition into the gaseous state.
Butane has a boiling point of 0.5 degrees centigrade
gas
When water reaches 0 degrees centigrade (32 degrees Fahrenheit) it begins to change to ice, a solid. This process of changing to ice can be very slow with the temperature changing throughout the day, water also doesn't instantly change to ice when the temperature hits 0 degrees centigrade, it takes time. The amount of time it takes varies on how far the temperature goes below 0 degrees centigrade. We also call 0 degrees centigrade (32 degrees Fahrenheit) the freezing point. To answer your question water can be either a solid or a liquid at the freezing point depending on if it's already ice, or it was water before.
gas
At 20 degrees Celsius, chlorine is in a gaseous state. Chlorine has a boiling point of -34 degrees Celsius at atmospheric pressure, so at 20 degrees Celsius, it would be a gas.
At 100 degrees Celsius, chlorine is in a gaseous state. Chlorine is a diatomic molecule with the chemical formula Cl2. At room temperature and pressure, chlorine exists as a greenish-yellow gas. As the temperature increases to 100 degrees Celsius, the kinetic energy of the chlorine molecules increases, causing them to move more rapidly and transition into the gaseous state.
Chlorine is a gas at everyday temperatures.
At 21 degrees Celsius, chlorine is a gas. Chlorine has a boiling point of -34 degrees Celsius and a melting point of -101 degrees Celsius, so at room temperature it exists in its gaseous state.
At 100 degrees Celsius, chlorine is in the gaseous state. Chlorine is a diatomic molecule normally found as a gas at room temperature and pressure.
It's a gas.
Below the boiling point (-29.15°F or -33.97°C) Chlorine is a liquid. At -66, it is not a gas.
Chlorine is a diatomic gas at room temperature and pressure, so it is in the gaseous state.
100 degrees Centigrade
Ethanol would be a gas (vapor) at 1000 degrees Farenheit, Centigrade or Absolute (Kelvin).
chlorine is a gas
It is in the gaseous state. The boiling point of chlorine is -34.4 degrees Celsius, therefore at room temperature of about 20-23.5 degrees Celsius, it is a gas. "Chlorine" is sometimes used colloquially to refer to compounds containing chlorine (or even, confusingly, compounds which do NOT actually contain chlorine), particularly those used as disinfectants in Swimming Pools. These might be solids, liquids, or solutions, depending on exactly what the compound is. Gas.
