specific heat, the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree. The units of specific heat are usually calories or joules per gram per Celsius degree. For example, the specific heat of water is 1 calorie (or 4.186 joules) per gram per Celsius degree

What is specific heat and its SI unit?
The SI unit for specific heat capacity is joule per kelvin per kilogram Jkg⋅K, J⋅K−1⋅kg−1. Since an increment of temperature of one degree Celsius is the same as an increment of one kelvin, that is the same as joule per degree Celsius per kilogram: J/(kg⋅°C).

What is specific heat CBSE Class 9?
The specific heat of an object is the amount of heat that is required to increase the temperature of unit mass of that particular substance through one degree. This is represented by the symbol 'c'. Its unit in SI is Joule /(kg°C) and in CGS is cal/(gm°C).

What is the formula unit of specific heat?
C = Q / (∆T m) is the formula. Answer: The heat or energy required during a constant volume process to change the temperature of a substance of unit mass by 1 °C or 1 °K is measured in J/kg K or J/kg C, as it is the heat or energy required to alter the temperature of a substance of unit mass by 1 °C or 1 °K.

What is specific heat and write its formula and units?
The specific heat is given by, C = Δ Q m Δ T. Henceforth, Heat required is given by Q = C m Δ T. = 830 J/KgoC × 0.6 Kg × 60oC. = 29880 J

Is specific heat a constant?
No, specific heat varies with temperatures. Only at temperatures way beyond the Debye temperature is the specific heat of the body a constant. This equation treats the specific heat as a constant because the temperature range of operation is assumed to be small enough for a constant assumption of specific heat.

Why is specific heat important?
Heat capacity or specific heat is the amount of heat per unit mass that is required to raise the temperature by 1°C. Specific heat is helpful in determining the processing temperatures and amount of heat necessary for processing and can be helpful in differentiating between two polymeric composites.

How is specific heat used?
High specific heat materials can be used as insulators. Wood, for example, has high specific heat. During the summer, wooden houses will keep the inside cooler. Builders can select appropriate building materials based on location and altitude.

What is called specific heat?

specific heat, the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree. The units of specific heat are usually calories or joules per gram per Celsius degree. For example, the specific heat of water is 1 calorie (or 4.186 joules) per gram per Celsius degree


What is specific heat simple?
Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat, meaning it takes more energy to increase the temperature of water compared to other substances.
