The amount of heat necessary to change a liquid to a solid at constant temperature?
None - heat is evolved, not required.
What is the amount of heat needed to change 1 kg of a specific material from liquid to vapor at a constant temperature?
The amount of heat needed to change 1 kg of a material from liquid to vapor at a constant temperature is called the latent heat of vaporization. This value varies depending on the material and is typically provided in joules/kg.
How much heat must be removed from steam to change it to a liquid?
The amount of heat that must be removed from steam to change it to a liquid is the latent heat of vaporization of water, which is approximately 2260 kJ/kg at atmospheric pressure. This is the amount of energy required for water to change from a gas to a liquid state at a constant temperature.
The heat of fusion is defined as the energy required at constant temperature to change 1 unit mass of a?
The heat of fusion is the amount of energy required to change 1 unit mass of a solid to a liquid at constant temperature.
The amount of energy needed to change a given mass of ice to water at constant temperature is called the heat of condensation crystallization fusion formation?
The amount of energy needed to change a given mass of ice to water at constant temperature is called the heat of fusion. This is the heat energy required to change a solid to a liquid at its melting point.
Why doesn't the temperature increase as the liquid change into gas?
When a liquid changes into a gas, it undergoes a phase change called vaporization. During this process, the energy is used to break the intermolecular bonds holding the liquid together instead of increasing the temperature. This is why the temperature remains constant during the phase change until all the liquid has converted into gas.
What change with the Henry law?
The formulation of Henry law is:"At constant temperature, the amount of a given gas dissolved in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid".
How is temperature used to recognize a phase change?
Temperature is used to recognize a phase change by monitoring the point at which the temperature remains constant during a transition from one phase to another. This constant temperature indicates a change in the internal energy of the substance rather than a change in temperature. This point is known as the melting point for solid to liquid transitions, and the boiling point for liquid to gas transitions.
What happen to the temperature when ice is heated?
During a phase change (from solid to liquid, as in melting and also from liquid to gas as in boiling) the temperature remains constant, as all of the energy is going to affecting the change, rather than raising the temperature. Once it has changed from solid to liquid, the liquid can then raise in temperature.
What is the heat of evaporation?
The heat of evaporation, also known as latent heat of vaporization, is the amount of energy required to change a substance from liquid to gas at its boiling point without changing its temperature. This energy is used to overcome the intermolecular forces holding the liquid together.
A curve showing the relationship between temperature and time for a given amount of liquid heated a constant rate is a what curve?
The curve showing the relationship between temperature and time for a given amount of liquid heated at a constant rate is called a "heating curve." This curve is mapped out on a graph.
What states that the solubility of gas is directly proportional to its pressure at a constant and specific temperature?
Henry's Law:At a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the Partial_pressureof that gas in equilibrium with that liquid.
