The amount of energy released by one kilogram of a substance at its freezing point?
The amount of energy released by one kilogram of a substance at its freezing point is known as the latent heat of fusion. This is the energy required to change a substance from a solid to a liquid state without changing its temperature. It is specific to each substance and measured in joules per kilogram.
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
What is a latent heat energy levels?
Latent heat- the amount of heat required by a system/ substance to change phase. It's also heat absorbed or radiated during a change of phase at a constant temperature and pressure.
What substance would absorb the most heat energy with the least change in temperature water or copper?
Copper would absorb more heat energy with less change in temperature compared to water due to its higher specific heat capacity. This means that copper can absorb more heat per unit mass before its temperature noticeably increases, while water's temperature would rise more easily when absorbing heat.
When a substance is undergoing a chance of state the temperature of the substance does not change until the?
change is complete
What processes absorb sensible heat?
Processes such as melting, boiling, and sublimation absorb sensible heat. Sensible heat is the heat required to change the temperature of a substance without a change in phase. When a substance undergoes these processes, it absorbs energy to break intermolecular forces and change its state.

This is the energy required to change a substance from a solid to a liquid state without changing its temperature. It is specific to each substance and measured in joules per kilogram.
The amount of heat needed to melt one kilogram of a substance?
The amount of heat required to melt one kilogram of a substance is known as the heat of fusion or the latent heat of fusion. It represents the energy needed to change a solid into a liquid at its melting point without a change in temperature.
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
What is a latent heat energy levels?
Latent heat- the amount of heat required by a system/ substance to change phase. It's also heat absorbed or radiated during a change of phase at a constant temperature and pressure.
What property of a substance does its specific heat capacity describe?
How much heat it takes to raise the temperature
How does specific heat of a substance relate to temperature change?
A substance with a high specific heat will easily change temperature.
How does the specific heat of a substance relate to temperature change?
A substance with a high specific heat will easily change temperature.
What substance would absorb the most heat energy with the least change in temperature water or copper?
Copper would absorb more heat energy with less change in temperature compared to water due to its higher specific heat capacity. This means that copper can absorb more heat per unit mass before its temperature noticeably increases, while water's temperature would rise more easily when absorbing heat.
What is the relationship between temperature change and the heat capacity at constant pressure?
The relationship between temperature change and heat capacity at constant pressure is that as the temperature increases, the heat capacity also increases. Heat capacity is a measure of how much heat energy is needed to raise the temperature of a substance by a certain amount, and it tends to increase with temperature because the substance can absorb more heat energy as it gets hotter.
What causes a substance to change a phase?
change in temperature
When a substance is undergoing a chance of state the temperature of the substance does not change until the?
change is complete
