What is the specific heat of solid?
In other words specific heat of a solid or liquid is the amount of heat that raises the temperature of a unit mass of the solid through 1° C. We symbolise it as C. In S.I unit, it is the amount of heat that raises the temperature of 1 kg of solid or liquid through 1K.
What solid has the highest specific heat?
Originally Answered: Which substance has highest heat capacity? You can look this up in many engineering tables. For elements: The lower the atomic number the higher the heat capacity in Joules/gram/degree Kelvin. Hydrogen is the winner with 14.304 followed by Helium with 5.193.
What material has highest specific heat?
Liquid water has one of the highest specific heat capacities among common substances, about 4184 J⋅kg−1⋅K−1 at 20 °C; but that of ice, just below 0 °C, is only 2093 J⋅kg−1⋅K−1. The specific heat capacities of iron, granite, and hydrogen gas are about 449 J⋅kg−1⋅K−1, 790 J⋅kg−1⋅K−1, and 14300 J⋅kg−1⋅K−1, respectively.
Is specific heat the same for all solids?
The specific heat of these solids exceeds that of the Debye prediction, even if they are electrical insulators, notably at the lowest temperatures; below 1 K, it varies approximately linearly with the temperature and has almost the same magnitude (to within a factor of 10) in all amorphous solids.
How do you find the specific heat capacity of a solid?
The specific heat capacity is the heat or energy required to change one unit mass of a substance of a constant volume by 1 °C. The formula is Cv = Q / (ΔT ⨉ m) .
What is specific heat and molar specific heat?
Specific heat is defined as the heat needed to raise the temperature of 1 gram of the substance by one degree (K or C). Molar heat is defined as the heat needed to raise the temperature of 1 Mole of the substance by one degree (K or C).
What is the specific heat of olive oil?
2.0 J/(g)
The specific heat of extra-virgin olive oil is 2.0 J/(g) (∘C), while the specific heat of water is 4.18J/(g) (∘C). Compared to water, olive oil has a low specific heat.
What has a low specific heat?
Metals such as iron have low specific heat. It doesn’t take much energy to raise their temperature. That’s why a metal spoon heats up quickly when placed in a cup of hot coffee. Sand also has a relatively low specific heat.
What has a specific heat of 1?
For example, the specific heat of water is 1 calorie (or 4.186 joules) per gram per Celsius degree.
What is specific latent heat?
Specific latent heat is the amount of energy required to change the state of 1 kilogram (kg) of a material without changing its temperature.
What does a Joulemeter measure?
A joulemeter is an electronic device used to measure the energy transfer by electricity in a circuit.
