Question: What is the specific heat capacity of ice, water and steam?...
What is the specific heat capacity of ice, water and steam?
Solution
Firstly we will define the term specific heat capacity. Then, we will continue with the specific heat capacity of ice, water and steam. The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius or Kelvin. This quantity is independent of the amount of substance.
Formula used:
c=mΔTQ
Complete answer:
The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius or Kelvin. This quantity is independent of the amount of substance.
The mathematical representation of the specific heat capacity is,
c=mΔTQ
Where c is the specific heat of water, m is the mass of the water, Q is the amount of heat required and ΔT is the change in temperature.
The substances, ice, water and steam represent the phases of matter, that is, the ice represents the solid, water represents the liquid and steam represents the gas.
Material | (J/kg K) | (J/g C) |
---|---|---|
Water | 4186 | 4.186 |
Ice | 2090 | 2.090 |
Steam | 2010 | 2.010 |
The values of the specific heat capacity mentioned may be rounded off to nearer values.
The specific heat capacity depends on the type of material and the phase of that material.
∴ The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius or Kelvin. The specific heat capacity of ice, water and steam are 4186J/kgK,2090J/kgK and 2010J/kgK.
Note:
The specific heat capacity is the property of the substance which determines the change in temperature of a substance without going under any phase change when the heat is absorbed or given out by it.
