Homework Answers
Answer:- For given situation ,it is called heat capacity.
Thus option B is correct.
Reason : According to defition ," amount of heat required to raise temperature of a substance by 1 degree centigrade is known as heat capacity.
Here why not we are taking specific heat capacity because for this , amount of heat required to raise temperature of unit mass of substance by 1 degree centigrade.
But in question not given the substance is of unit mass . That's why answer will be heat capacity.
Hi any doubts leave a comment... THANKS

When 0.0700 mol of a substance is added to 150.0 grams of an aqueous solution in a Styrofoam cup calorimeter, a chemical reaction occurs that causes the temperature of the solution to increase from 25.3 to 38.3 °C. Assume that the specific heat of the solution is 4.18 J/(g°C) and that the heat capacity of the calorimeter is negligible. Use this data to calculate the enthalpy change (in kJ/mol substance) for the chemical reaction +116 kJ/mol +3.80 kJ/mol -571 kJ/mol...

If 101J of heat was removed from 50g of an element at 20C with a specific heat of 0.5. a) What is the final temperature of the element? b) How is the answer different because heat is removed vs added? (I think the answer to b is that if heat is removed it is exothermic so q is negative?)
