Which element has the lowest specific heat capacity?
Anonymous’ answer is spot on:
- High: Hydrogen (H), C ≈ 14.30 J/(mol·K)
- Low: Radon (Rn), C ≈ 0.09 J/(mol·K)
What is the specific heat capacity of iron?

Does iron have a low specific heat?
Metals such as iron have low specific heat. It doesn’t take much energy to raise their temperature.
Why does iron have a low specific heat capacity?
Metal atoms in pure metal are very close together and are able to transfer heat easily via conduction from one atom exciting the other atoms next to it. So the amount of energy it takes to heat a metal is relatively small to that of water for example.
What does low heat capacity mean?
Heat capacity is related to a substance’s ability to retain heat and the rate at which it will heat up or cool. For example, a substance with a low heat capacity, such as iron , will heat and cool quickly, while a substance with a high heat capacity, such as water , heats and cools slowly.
Does air have a low heat capacity?
Heat capacity of air is not particularly low, nor is it high. In fact, it is the same as that of any other diatomic gas, even though the table might seem to suggest otherwise.
What is the specific heat capacity of steel?
420 J/kg°C
Steel: 420 J/kg°C.
What does a lower specific heat capacity mean?
A low value means that it does not take very much energy to heat or cool it. Adding heat to a “low specific heat” compound will increase its temperature much more quickly than adding heat to a high specific heat compound.
Does copper have a low specific heat capacity?
Indicates understanding that copper has a lower specific heat capacity than aluminum. Indicates that the change in temperature of the metal was greater for copper (when hotter metal is added to cooler water) or the change in temperature of the water was less for copper (when hotter metal is added to cooler water).
When a particular substance is said to have a low specific heat capacity it means that the substance?
A low specific heat means the substance will change temperature easily. Water ,which makes up a great deal of the surface of the Earth has a very high specific heat . Heat capacity can be used to compare how easily two objects will change temperature.
What is the low specific heat of liquid?
Having low specific heat means it needs lower amount of heat for the purpose. For example case-1 needs 100 kJ(assume) of heat and for case-2 specific heat is lower means it require 50 kJ(assume) of heat. It means that how many heat is needed to increase the temperature of the object under consideration by 1K .
