A cubic meter of gas at standard temperature and pressure will have approximately 2.6 x 1025 molecules. This is based on the Avogadro's Number of molecules, (approximately 6.022 x 1023) taking up a volume of around 23 liters. Alternatively, 32 grams of oxygen has Avogadro's number of molecules.
What else can I help you with?
Is n2 a solid at room temperature?
N2 is not solid at room temperature. This is one of the diatomic elements that are in the gaseous state at room temperature.
How does water at room temperature become gas?
The process of transforming water to gas in room temperature is evaporation. Some fraction of water molecules obtain enough energy to change into vapor.
Why is water liquid at room temp but oxygen is gas at room temp?
Water molecules have stronger intermolecular forces (hydrogen bonding) that keep them together as a liquid at room temperature. Oxygen molecules have weaker intermolecular forces, so they stay as a gas at room temperature.
Why does water at room temperature in a cup evaporating?
Water is evaporated at any temperature because the movement of water molecules is continuous and some molecules at the surface can escape as a gas.
Is salt a sloid liquid or gas at room temperature?
Salt is a solid at room temperature. It typically exists in crystalline form as a solid due to the arrangement of its molecules.
What is chlorine cl phase at room temperature?
Chlorine is a gas at the room temperature and pressure.
What is a hydrogen at room temperature?
At room temperature, hydrogen is a colorless, odorless, and tasteless gas. It is the lightest and most abundant element in the universe. Hydrogen molecules consist of two hydrogen atoms bonded together (H2).
What is the boiling point of chlorine at room temperature?
Chlorine is a gas at room temperature. Boiling point of it is 34.6 degrees Celsius. It stays as diatomic molecules.
Is n2 a solid at room temperature?
N2 is not solid at room temperature. This is one of the diatomic elements that are in the gaseous state at room temperature.
How many degrees is nitrogen at room temperature?
Nitrogen is a gas at room temperature and typically exists as N2 molecules, which do not have a specific temperature. However, the boiling point of nitrogen is -195.79 degrees Celsius, which means it would be a gas at room temperature around 20 degrees Celsius.
Does methane exist as separate molecules?
Yes, because it's a gas at room temperature
How does water at room temperature become gas?
The process of transforming water to gas in room temperature is evaporation. Some fraction of water molecules obtain enough energy to change into vapor.
Is ammonia a gas at room temperature a intensive or extensive?
Ammonia is a gas at room temperature and is considered an intensive property because it does not depend on the amount of ammonia present in the system.
Why is CO2is gas in room temperature?
Carbon dioxide cannot make strong enough bonds between the molecules to be a liquid or a solid, in the room temperature and pressure.
Why does liquid bromine change to gas at room temperature?
Liquid bromine has weak intermolecular forces, which allow individual molecules to easily overcome these forces and escape into the gas phase at room temperature. This is why liquid bromine evaporates and changes into a gas.
Why is water liquid at room temp but oxygen is gas at room temp?
Water molecules have stronger intermolecular forces (hydrogen bonding) that keep them together as a liquid at room temperature. Oxygen molecules have weaker intermolecular forces, so they stay as a gas at room temperature.
