Answer By exposing materials to a hot flame (from a Bunsen burner typically), the color of the flame can be used to identify the material. Certain elements give off a characteristic color when heated to high temperature. See the Related Links for "Wikipedia: flame test" to the bottom for the answer.
A method of obtaining an emission spectrum from a sample
specific heat capacity of a substance is defined as the QUANITY OF HEAT REQUIRED to raise the temperature of 1 Kg of the substance through 1K ( kelvin ) .
however it obtained the unit of J/kg/k
The specific heat capacity is the energy required to raise the temperature of 1 kg of material by 1 degree Celsius.

Apex: The energy needed to change the temperature of a substance The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius.
The frequency of a wave, represented by the letter f, is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. The SI unit of cycles per second is called hertz or Hz. Hz can be expressed as a reciprocal second (s-1 or 1/s).
The number of waves that pass a point in 1 second
The reaction is exothermic.
