Water remains liquid over the greatest temperature range compared to most other substances. It spans from 0°C (32°F) to 100°C (212°F) under standard atmospheric pressure. This wide liquid range is crucial for various biological and ecological processes, making water essential for life on Earth. Other substances, like certain organic solvents, may also have wide ranges, but water's unique properties make it particularly significant.
What else can I help you with?
What is the temperature of a pure solid substance?
The temperature of a pure solid substance remains constant during its phase transition from solid to liquid until all the solid has melted. This temperature is known as the melting point of the substance.
What temperature at which a substance in the liquid phase transforms to the gaseous phase refers to the substances?
The temperature at which a substance in the liquid phase transforms to the gaseous phase is called the boiling point for pure substances. It is a characteristic property of the substance and remains constant under a specific pressure.
What two factors determine if a substance will be a liquid?
The temperature of the environment and the melting and evaporation temperature of the substance.
How does a substance's boiling point determine its state at room temperature?
A substance's boiling point indicates the temperature at which it transitions from a liquid to a gas. If the substance's boiling point is below room temperature, it will be a gas at room temperature. If the boiling point is above room temperature, it will be a liquid at room temperature.
A substance change from a solid to a liquid at its?
A substance change from a solid to a liquid at its boiling point. This is when it reaches a certain temperature.
Which substance remains a liquid over a largest temperature range?
Water remains a liquid over a large temperature range.
What is the temperature of a pure solid substance?
The temperature of a pure solid substance remains constant during its phase transition from solid to liquid until all the solid has melted. This temperature is known as the melting point of the substance.
What does the flat line on cooling curves represent?
The flat line on a cooling curve represents the phase transition of a substance from liquid to solid. During this phase transition, the temperature remains constant as the substance changes from a liquid state to a solid state.
How does temperature vary when a substance changes from solid to liquid?
When heat is applied to a solid, its temperature rises until it reaches the melting point of the substance. As the heat application continues, the temperature remains constant at the melting point as all of the heat is consumed in changing the state of the substance from solid to liquid. It is only after the conversion to liquid is complete that the temperature of the substance again starts to rise as long as heat is still being applied.
What temperature at which a substance in the liquid phase transforms to the gaseous phase refers to the substances?
The temperature at which a substance in the liquid phase transforms to the gaseous phase is called the boiling point for pure substances. It is a characteristic property of the substance and remains constant under a specific pressure.
How can you add heat to a substance without raising its temperature?
One way to add heat to a substance without raising its temperature is by changing its state of matter. This process, known as phase change, involves adding heat energy to a substance to change it from a solid to a liquid or from a liquid to a gas. During this phase change, the temperature of the substance remains constant until the phase change is complete.
What is the temperature at which a substance becomes a liquid?
depends of the substance
What is the temperature called at which a substance changes from a solid to a liquid?
The temperature at which a substance changes from a solid to a liquid is called the melting point.
The amount a liquid holds?
The amount of a substance that a liquid holds will be the solubility of that substance in that volume of the liquid - at that temperature.
Which matter remains liquid at room temperature?
Mercury is the only metal that remains liquid at room temperature.
Does temperature affect critical pressure?
Temperature does not directly affect critical pressure. Critical pressure is a characteristic property of a substance and remains constant regardless of temperature. At the critical point, the substance exists as a single phase, with distinct liquid and gas properties disappearing.
What is temperature at which a substance changes from a solid to liquid?
The temperature at which a substance changes from a solid to a liquid is known as its melting point.
