Question

Which substances are having specific
heat is half in C.G.S. system?​

Answer 1

Answer:

If an amount of heat ∆Q is needed to raise the temperature of M mass of a substance through ∆T, then it is called specific heat capacity. The CGS unit of specific heat is cal g-1 ℃-1 and SI units is J kg-1 K-1.

Answer 2

It depends on the nature of the substance and its temperature.

C.G.S. system:

A variation of the metric system using the centimeter as the unit of length, the gram as the unit of mass, and the second as the unit of time is known as the centimeter-gram-second system of units (abbreviated CGS).

Specific heat  in the C.G.S. system:

• The quantity of heat necessary to increase the temperature of the substance's unit mass by one degree is known as a substance's specific heat.
• It depends on the substance's properties and temperature.
• Specific heat capacity is the measure of how much heat (Q) is required to raise the temperature of a substance (M mass) by (T).
• Cal g-1 °C-1 is the CGS unit of specific heat, while J kg-1 K-1 is the SI unit.
