What is an endothermic reaction
a chemical reaction in which the reactants absorb heat energy from their surroundings to form the products.
What is an exothermic reaction
A chemical reaction in which the reaction process releases heat energy to its surroundings.
When does a combustion reaction occur
When a substance reacts with oxygen and energy is released.
What is the specific heat capacity of a substance
It is the amount of energy required to heat that substance by 1 degree Celsius.
what is the equation for specific heat capacity
Eh=cmx(change in temp)
Change the subject to c - from the specific heat capacity (Eh=cm x change in temp
c=Eh/(m x change in temp)
what is specific heat capacity measured in
J/kg°C
