Interpretation:
The energy required to heat
Concept Introduction:
Temperature: It is measured of the amount of heat energy in an object, is commonly reported in Fahrenheit
Specific heat: It is a
The variation ranges of specific heat values are seen for substances depending on the extent to which they absorb heat.
In other words the amount of heat needed to raise the temperature of (1 gm) of a substance by
