Specific heat for hydrogen

What is the substance with the highest specific heat?

WebFeb 26, 2015 · Specific heat capacity is defined as the amount of heat required per unit mass to increase the temperature by a degrees celsius. The relatively low molar mass of water allows more moles of it to be there in a mass unit (either kg or g) As a side note, the exceptional high specific heat is not the only weird property of water. See here for example. WebSpecific Heat Formula: Heat capacity formula is: C = Q m × Δ T Whereas: C is representing the specific heat capacity Q is representing the induced thermal energy m is representing the mass Δ T is the temperature difference J is Joule ° C is degrees centigrade or Celsius K is kelvin Example:
