The higher the substance's specific heat capacity, the more heat energy is needed to raise it's temperature.

Would substances with high specific heat capacity also have high temperatures?
Specific heat capacity is the amount of energy or heat required to raise the temperature of a unit mass of a substance by one kelvin. So if the specific heat capacity is high then you would require more energy or heat to raise its temperature. The specific heat capacity does not really have anything to do with how much you can increase an objects temperature. IT HAS TO DO WITH THE ENERGY NEEDED TO INCREASE THE TEMPERATURE.
How would you go about finding the specific heat of Glycerin?
The specific heat of any substance can be found by calculating the amount of heat required to raise a unit mass quantity of it by 1 degree. The relationship between heat and temperature change is Q=cm(change in T) where Q is heat in Joules, c is the specific heat, m is the mass, and T is the temperature.
Is it true that it takes a lot of heat to melt a substance with a low melting point?
See the expert answer above for a specific answer to the question. However, if you mean 'what is a low melting point' then it means that the temperature at which the substance becomes a liquid is reasonably easy to get to, so you have to provide less heat to get to the melting point than you would if it were high.
Would fevers run higher or lower if liquid water's specific heat were not so high?
Fevers would run higher if liquid water's specific heat were lower. The amount of energy need to raise our body temperature would be less. Although the body would still develop control mechanisms to regulate the temperature to prevent heat death of the cells.
Is The density of a substance is the same for all samples of the substance?
Not necessarily. The temperature of the samples would have to be the same. It can also vary with how pure the substance is.
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 specific heat capacity of fish source?
To work out the specific heat capacity of fish source sauce you would need to first find out the amount of heat required to raise the temperature of 1g of the substance by 1oC
How would you calculate how much heat energy is required to raise the temperature of coal?
The same as you would calculate for any other substance. You have to multiply all of the following: • The desired temperature difference. • The mass of the sample. • The specific heat, in this case, of coal.

How does a substance with low specific heat cool down or heat up?
I think slowly because a substance that heats up quickly have a high specific heat capacity. i think slowly Specific heat is that amount of energy needed to raise a unit mass by a unit temperature. If something has a high specific heat, it means it needs a lot of energy to heat up, meaning slow.
How much does one calorie raise the temperature of 1 kilogram of water?
One Calorie or one kilocalorie raise the the temperature of one kilo gram of water by one degree Celsius. Here the 'C' is capital. Your calorie raises the temperature of one milliliter of water by one degree Celsius. Here the 'c' is small.

What would increase the temperature of the substance?
increasing energy Work increases the temperature of a substance due to friction.
Define heat capacity and specific heat capacity?
Heat capacity is The ratio of the heat energy absorbed by a substance to the substance's increase in temperature. The quantity of heat required to raise a unit mass of homogeneous material one unit in temperature along a specified path, provided that during the process no phase or chemical changes occur, is known as the heat capacity of the material. Moreover, the path is so restricted that the only work effects are those necessarily done on the surroundings to cause the change to conform to the specified path. The path is usually at either constant pressure or constant volume. In accordance with the first law of thermodynamics, heat capacity at constant pressure Cp is equal to the rate of change of enthalpy with temperature at constant pressure (?H/?T)p. Heat capacity at constant volume Cv is the rate of change of internal energy with temperature at constant volume (?U/?T)v. It is usually expressed as calories per degree in terms of the amount of the material being considered. Heat capacity and its temperature variation depend on differences in energy levels for atoms. Heat capacities are measured with a calorimeter and are important as a means of determining the entropies of materials.
Would you raise or rise the temperature?
Raise would be correct in this situation. Can you specify the exact sentence it is in in a new question?
Which would require a greater amount of heat water or iron?
To raise the temperature of both an equal amount, water would require more energy. In terms of the energy required to raise the temperature: iron = 0.45 joules / gram . kelvin water = 4.2 joules / gram . kelvin This is known as the specific heat capacity of a material
