Which of the following represents the quantity of heat required to raise the temperature of one gram of a substance by one degree Celsius?

Heat of reaction

Boiling point

Specific heat capacity  

Thermochemical value

Explanation:

The specific heat capacity is a physical quantity that is defined as the amount of heat that must be supplied to the mass unit of a thermodynamic substance or system to raise its temperature by one unit.

The answer is: Specific heat capacity.

The correct answer is "Specific heat capacity"

Explanation:

Specific heat is a physical quantity that expresses the amount of heat that a substance requires per unit mass for its temperature to increase by one unit. In other words, it is the amount of heat required to raise the temperature of one gram of substance by one degree Kelvin or Celsius.

Being Joules (J) in the International Measurement System the unit for heat, the specific heat is expressed in this system in joules per kilogram and per kelvin (J.Kg⁻¹.K⁻¹). Another common form of measurement involves the use of calories per gram and per degree centigrade (cal.g⁻¹. ° C⁻¹)

So, the correct answer is "Specific heat capacity"

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
