One possibility is volume. For instance, a gallon of water has more potential energy than a glass of water.
Temperature has nothing to do with heat capacity.

∙ 10y agoSpecific heat capacity or SHC is defined (In chemistry at least) as: The amount of energy required to raise one gram of a substance by one kelvin.
Due to the weights of different molecules lighter substances contain more particles for a given weight and because all the particles are heated evenly (due to the property that a closed systems will seek to obtain a thermal equilibrium) lighter substances will have a higher SHC because there are more particles per gram
e.g.
The SHC of Hydrogen, which has an atomic weight of 1.008 AMU's is ~14.3
The SHC of Oxygen, which has an atomic weight of 16 AMU's is ~0.918
As you can see because hydrogen is ~16 times smaller than Oxygen, the increased number of particles per gram means that a lot more energy is required to raise them all by one kelvin
CORRECTION: Specific heat capacity or SHC is defined (In chemistry at least) as: The amount of energy required to raise one gram of a substance by one DEGREES CELSIUS

∙ 10y agoThe specific heat capacity of different substances is different because substances do not have the same molecular mass. Molecular mass is the total weight of the atoms or molecules of a substance.

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.
Substance A has a higher heat capacity than does substance B and substance B has a higher heat capacity than does substance C. If you add the same amount of heat to all three which order shows the pro?
c
What happens to heat capacity if mass id doubled?
Heat capacity is measured either for one gram or one mole of a substance so the mass of substance does not matter.
What is the quantity of heat energy required to raise the temperature of a unit mass of a substance?
If the substance is water, this is the kilocalorie (1000 calories). One calorie is the heat to raise one gram of water by 1 deg C. Other substances don't have the same specific heat capacity as water, so you have to correct for that, first find out the heat capacity (specific heat) for the substance you are dealing with.
Which substance having high specific heat capacity?
A common substance with a high specific heat is water. There are a few substances that have a higher heat capacity than water, though, such as lithium and ammonia.
If you were trying to find a substance that increases in temperature rapidly you should choose a substance with?
A substance with a low heat capacity.A substance with a low heat capacity.A substance with a low heat capacity.A substance with a low heat capacity.
What is heat capacity of a substance?

Capacity of a substance to do work?

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.
Substance A has a higher heat capacity than does substance B and substance B has a higher heat capacity than does substance C. If you add the same amount of heat to all three which order shows the pro?
c
How is specific heat of a substance different from the heat capacity?
Imagine 1 kg of water. This has a heat capacity. Now if you have 1000kg of water the heat capacity is obviously greater. The Specific Heat Capacity is a material constant. It specifies a set quantity. For water it is 4.184 kiloJoules per kilogram per Kelvin.
What factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
When heating two substance with same heat the temperature raises on two substance are different why?
Each substance has a different heat capacity, which means they need different amounts of energy to change temperature by the same amount (for a given mass). If the same amount of energy is input, then the temperature difference will also be different.
What happens to heat capacity if mass id doubled?
Heat capacity is measured either for one gram or one mole of a substance so the mass of substance does not matter.
What is the quantity of heat energy required to raise the temperature of a unit mass of a substance?
If the substance is water, this is the kilocalorie (1000 calories). One calorie is the heat to raise one gram of water by 1 deg C. Other substances don't have the same specific heat capacity as water, so you have to correct for that, first find out the heat capacity (specific heat) for the substance you are dealing with.
Does a thermometer bulb have large heat capacity or small heat capacity?
A thermometer bulb should have.small heat capacity. In case if it has large capacity, the temperature of the substance will get lowered due to the large amount of heat absorbed by the thermometer bulb
Which substance having high specific heat capacity?
A common substance with a high specific heat is water. There are a few substances that have a higher heat capacity than water, though, such as lithium and ammonia.
