What is the specific heat of a 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.
Do solids have specific heat?
Also in case of solid, the values of Cp and Cv remains almost same, hence solid has only one specific heat. By definition,The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius.
What is the conclusion of calorimetry?
4 CONCLUSIONS The very great advantage of calorimetry is that it is completely non-specific, which means that almost any type of biological reaction or process may be measurable with calorimetry. The limit may be the sensitivity of the instrument.
What materials determine the specific heat of a solid?
In order to find or determine the specific heat of solid experimentally, We require a calorimeter, thermometer, stirrer, water, stem heater, lead shots and wooden box.
Why is specific heat important?
Explanation: Specific heat capacity is a measure of the amount of heat energy required to change the temperature of 1 kg of a material by 1 K. Hence it is important as it will give an indication of how much energy will be required to heat or cool an object of a given mass by a given amount.
How do you find the specific heat of a solid?
Q = m*s*dT, where Q = heat, m = mass, s = specific heat, and dT is the change in temperature (T2 – T1). You can use this formula to calculate the specific heat.
How does specific heat of solids vary with temperature?
In the context of thermodynamics, the specific heat capacity is defined as the required heat energy to increase the one-degree temperature of the substance per unit mass. If the energy within the molecule of the substance increases, then the specific heat of the substance also increases.
What is the importance of temperature change in assessing specific heat?
When an endothermic reaction occurs, the heat required is absorbed from the thermal energy of the solution, which decreases its temperature. The temperature change, along with the specific heat and mass of the solution, can then be used to calculate the amount of heat involved in either case.
What are the values of specific heat capacity?
For liquid at room temperature and pressure, the value of specific heat capacity (Cp) is approximately 4.2 J/g°C. This implies that it takes 4.2 joules of energy to raise 1 gram of water by 1 degree Celsius.
Why specific heat is different for different materials?
Each substance will have a different mass, so when the amount of heat and the change in temperature are held constant, the only variable is the mass. Therefore, because mass is the only variable, so because substances have different masses, they will have different specific heats.
What is the conclusion of specific heat capacity?
Conclusion: The specific heat capacity of Alumium is 900J/Kg/K and the specific heat capacity of Lead is 1300J/Kg/K. This is as I predicted. This means that it takes more energy to change the temperature of lead than of Aluminium.
How is specific heat used in everyday life?
Uses of specific heat in daily life Substances having a small specific heat capacity, are very useful as material in cooking instruments such as frying pans, pots, kettles and so on, because, when small amount of heat is applied it will heat quickly. Water used in fire fighting.
