Measuring the Quantity of Heat - Questions
The Measuring the Quantity of Heat Concept Builder is comprised of 16 multi-part, numerical questions spread across three difficulty levels. Students will receive one question for each difficulty level. Questions involve either the completion of a sentence (Apprentice Level) or the completion of a table (Master and Wizard Levels). The Concept Builder is coded to select at random a question for each level.
The three Difficulty Levels in this Concept Builder differ only in terms of the number of blanks that must be filled and the complexity of the given numbers. Here is the breakdown of the levels:
- Apprentice Difficulty Level: Questions 1-4 ... Students complete five sentences by providing a numerical value for a blank bu using the Q=m•C•∆T equation.
- Master Difficulty Level: Questions 5-10 ... Students complete a five row table relating Q, m, ∆T, Ti, and Tf. There are two blanks in each row.
- Wizard Difficulty Level: Questions 11-16 ... Students complete a five row table associated with the use of calorimetry to determine the heat of reaction in kJ/mol. There are three blanks in each row.
The questions from each group are shown below. Teachers are encouraged to view the questions in order to judge which difficulty levels are most appropriate for their classes. Alternatively, teachers can do the
Concept Builder to gain a feel for the student experience..
