The amount of energy required to raise the temperature of 1 kilogram of a substance by 1 kelvin is called?
Simple answer:
That number is dependent on a factor called the specific heat with units of energy per mass unit per degree of temperature change. For water and using metric units, that specific heat is about 4.2 kilowatt seconds per kilogram per degree. A watt-second is known as a Joule (J) in the SI system of units. In SI units temperature is expressed in Kelvin (K) which is like Celsius (C) but shifted by approximately positive 273. Mass is expressed in kilograms (kg) in SI units.
So if the substance is water 4200000 Joules (J) or 4.2 MJ of energy would be required.
E = 4.2 (kJ/kg/degK x 1kg x 1000 degK
E = 4200 kJ
E = 4.2 MJ.
Problems with a simple answer:
No material has an absolutely constant specific heat as it is heated and most will experience phase changes which make the calculations more difficult and specific to the material being heated. Each of the physical phases between the starting temperature (in the case of water that could be ice, liquid, steam) has to be calculated separately in a stepwise (but computationally similar) process. Finally ionization occurs in the material leading to the plasma state and this energy of electrical dissociation must also be taken into account.

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 temperature an element?
Temperature is a physical quantity that measures the degree of hotness or coldness of an object. It is not considered an element in the traditional sense of the term, as it is a property of matter rather than a distinct substance with specific characteristics.
The total amount of energy of a substance is?
The total amount of energy of a substance is typically defined as its internal energy, which includes both the kinetic and potential energies of the particles that make up the substance. This energy can also include contributions from external factors like pressure and temperature.
What amount of heat needed to increase the temperature of a 1-kilogram substance by 1 and degC is known as the?
The amount of heat needed to increase the temperature of a 1-kilogram substance by 1 degree Celsius is known as the specific heat capacity of the substance. It is a measure of how much heat energy is required to raise the temperature of a given mass of the substance by one degree Celsius.

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.
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 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 the amount of cooling required to low the temperature of a substance through 1 degree Celsius?
The amount of cooling required to lower the temperature of a substance by one degree Celsius is known as the substance's specific heat capacity. It depends on the substance's properties and can be measured in joules per gram per degree Celsius (J/g°C) or in joules per kilogram per degree Celsius (J/kg°C).
What is specific heat a measure of?

The amount of heat needed to increase the temperature of one kilogram of substance by 1 and degc?
The amount of heat needed to increase the temperature of one kilogram of a substance by 1 degree Celsius is known as the specific heat capacity of the substance. It is measured in joules per kilogram per degree Celsius (J/kg°C). Different substances have different specific heat capacities due to their molecular structure and composition.
What does it mean to say that a material has a high or low capacity?
The specific heat capacity of a substance is the amount of energy required to increase the temperature of a said substance 1o K. The capacity is measured in kilojoules divided by kilogram time degrees Kelvin (kJ/Kg k). So, if the specific heat capacity of a substance is high, it requires a very large amount of energy to increase the temperature, and if it has a low specific heat capacity, the required energy will be lower.
What term describes the amount of thermal energy that is required to raise the temperature of a substance by 1.0 degrees Celsius?
Specific heat capacity is the term that describes the amount of thermal energy required to raise the temperature of a substance by 1.0 degree Celsius.
What is the substances specific heat?
Specific heat is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius. Each substance has its own specific heat capacity, which is a physical property unique to that material. It is typically measured in joules per gram per degree Celsius (J/g°C) or in joules per kilogram per degree Celsius (J/kg°C).
What is the heat capacity equation and how is it used to calculate the amount of heat required to change the temperature of a substance?
The heat capacity equation is Q mcT, where Q represents the amount of heat energy, m is the mass of the substance, c is the specific heat capacity of the substance, and T is the change in temperature. This equation is used to calculate the amount of heat required to change the temperature of a substance by multiplying the mass, specific heat capacity, and temperature change.
