Specific Heat - Chemistry |

Specific heat represents the amount of heat required to change a unit mass of a substance by one degree Celsius. This is expressed mathematically as: #q = m * c * DeltaT#, where #q# - the amount of heat supplied; #m# - the mass of the substance; #c# - the respective substance\'s specific heat; #DeltaT# - the change in temperature. So, if we want to determine the units for specific heat, we\'ll
