To calculate the amount of heat absorbed as a substance melts what information is not needed?
the density of the sample.
What is specific heat a measure of?
The amount of energy it takes to change the temperature of a substance by a certain amount. How much energy it takes to heat a substance ~APEX
The amount of heat required to raise the temperature of 1 gram of water 1 degree Celsius is called?
The amount of energy required to raise 1 kg of a substance by 1 degree Celsius is called the "Specific Heat Capacity," or just specific heat, of a substance. This is an intensive property of the particular substance.
Is heat lost gained or absorbed during sublimation?
Sublimation of a substance, for example, of frozen carbon dioxide or dry ice, involves the substance's absorbing heat energy from its surroundings. Hence, the dry ice itself gains the energy needed to change from solid to gas, and the surroundings lose the energy, and indeed are perceived as colder.

Which heats up faster air or soil?
The specific heat of a substance is the amount of heat energy it takes to raise the temperature of the substance 1o C. A substance with a high specific heat requires more heat to increase in temperature than a substance with a low specific heat.Air has a specific heat of about 1.005 Kj/Kg/degree C.Most soils are mostly composed of mineral particles, air and water. The specific heat of dry soil is about 0.80 Kj/kg/degree C. However, since the specific heat of water is very high (4.2 Kj/kg/degree C), soils often have a higher specific heat than air, and heat up more slowly than the air.So it ultimately depends on the amount of moisture in the soil. A bone-dry soil can heat up quicker than air, but a wet soil will take longer to heat up than the air.
What is the amount of energy required to raise the temperature of 1 kilograms of a substance by 1 kelvin is called?
Specific heat is the amount of heat needed to melt one kilogram of a substance...heat of fusion
The amount of energy released by one kilogram of a substance at its freezing point?
Heat of Fusion
What is The amount of energy required to raise the temperature of one KG of a substance by one KG is determined by its?
according to my research specific heat is needed to raise the temperature.
To calculate the amount of heat absorbed as a substance melts what information is not needed?
the density of the sample.
When 1 kg of a substance changes from solid to liquid at its melting point it must absorb an amount of heat equal to which of the following?
It must absorb heat equivalent to its specific latent heat (Kilojoules per kilogram).
What is the heat required to change the temperature of 1 gram of a substance?
The amount of heat needed to raise the temperature of 1 gram of a substance 1 degree celsius varies depending on the substance. This value is called the specific heat.
What is a substance that has a specific heat?
Every substance has a specific heat. The definition of specific heat is: The amount of energy, usually measured in calories, needed to raise the temperature of one gram of a certain substance by one degree Celsius.
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 is molar heat?
Different substances have varied molar heat capacities. The molar heat capacity of a substance refers to the amount of heat energy needed to raise 1 mole of that substance by 1 degree Celsius.
What is the amount of energy needed to change the temp of a substance called?
The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius
What is the amount of heat needed to increase the temperature of a certain mass of a substance by 1 degree Celsius?
The heat capacity of a substance is the amount of heat required to raise the temperature of a defined amount of pure substances by one degree (Celsius or Kelvin). The calorie was defined so that the heat capacity of water was equal to one.
Is less energy needed for objects with high specific heat capacity?
More specific heat means you need more heat energy to, for example, raise one kilogram of a substance by one degree centigrade.
