Sagot :
Specific heat capacity of a substance is the amount of heat required to raise the temperature by one degree Celsius of one gram of a substance. Therefore, student a and student b are correct.
What is Enthalpy?
Enthalpy term is basically used in thermodynamics to show the overall energy that a matter have. Mathematically, Enthalpy is directly proportional to specific heat capacity of a substances.
Mathematically,
q = n ×ΔH
where
q = amount of heat
n = no of moles
ΔH = enthalpy
n = w / M.M
Both students are correct as energy can be positive as well as negative. Any reaction in which energy is added, energy value comes out to be positive and reaction is called endothermic reaction. Any reaction in which energy is released, energy value comes out to be negative and reaction is called exothermic reaction.
Therefore, student a and student b are correct.
