Why oxygen is gas but water is a liquid at room temperature?
Water molecules are strongly attracted to each other, so they remain condensed (that is, a liquid, and not a gas) at higher temperatures. Dihydrogen and dioxygen have no strong attractive forces to hold the molecules together, so they exist as gases at room temperature and pressure (that is, in our everyday lives).
Why oxygen is gas at room temperature?
Oxygen is a non-metal element and is found naturally as a molecule. Each molecule is made up of two oxygen atoms that are strongly joined together. Oxygen has low melting and boiling points, so it is in a gas state at room temperature.
Is oxygen in water a gas or liquid?
Dissolved oxygen (DO) is oxygen gas (O2) that is dissolved in water. Gases in the atmosphere, such as oxygen, nitrogen and carbon dioxide, naturally dissolve in water to some degree. Like salt or sugar, these gases are invisible in water once they become dissolved. The element oxygen exists in many forms in nature.
Why is water is liquid in room temperature?
Water at room temperature is liquid due to the presence of hydrogen bond. These bonds hold water molecules together for small fractions of a second. Water molecules move continuously. This property makes the water liquid at room temperature.
Why does water not evaporate and become a gas at room temperature?
The heat in that water results in some molecules moving fast enough to escape into the air, that is, evaporate. No additional source of energy is required for evaporation, and the water does not need to reach the boiling point to evaporate. As we’ve seen, water will evaporate at room temperature.
Why is water liquid at room temperature class 9?
A fixed mass of water occupies a fixed volume. (ii). Water at room temperature does not have a fixed shape but flows to take the shape of the container. Hence, water at room temperature is a liquid.
At what temperature is oxygen a liquid?
297.3 degrees Fahrenheit
Here are two other points to be aware of relating to the temperature and vaporization hazards: Liquid oxygen boils at –297.3 degrees Fahrenheit and is extremely cold.
Why oxygen is a gas at room temperature class 9?
Explanation: However, each oxygen molecule is held to the other by weak intermolecular or Van der Waals forces. Hence, a low amount of energy is required to overcome these weak forces and oxygen has a low boiling point. Therefore, at room temperature, oxygen is a gas.
What is the temperature of oxygen gas?
| Oxygen | |
|---|---|
| Physical properties | |
| Phase at STP | gas |
| Melting point | (O2) 54.36 K (−218.79 °C, −361.82 °F) |
| Boiling point | (O2) 90.188 K (−182.962 °C, −297.332 °F) |
Is oxygen a solid liquid or gas at room temperature?
Oxygen is a gas at room temperature. If the normal melting point of a substance is below room temperature, the substance is a liquid at room temperature.
Why is water liquid at room temperature Brainly?
At room temperature (25°C), water is a liquid because it has the following characteristics of liquid: At room temperature, water has no shape but has a fixed volume i.e., it occupies the shape of the container in which it is kept. At room temperature, water flows easily.
