Suppose That You Are Trying to Solve the Problem of Assembling

question 18

Multiple Choice

Suppose that you are trying to solve the problem of assembling a new bookcase that you have just bought, using a sheet of instructions as a guide. According to the discussion of problem understanding,

• A) you must use heuristics in order to understand a problem.
• B) a problem will have a coherent representation, as long as you have used your background knowledge about your previous experiences with assembling items.
• C) you need to mentally represent the problem, and this representation must be consistent with the assembly instructions.
• D) the major component of this phase of problem solving is the decision to use symbols and visual images to represent the various steps that are illustrated in the assembly instructions.

Temperature Vs. Heat

Temperature measures the kinetic energy of particles in an object, while heat refers to the transfer of energy from one object to another because of a temperature difference.

Plateau

A plateau is a flat or level portion of a graph, or similarly, an area of land that is relatively flat and elevated above the surrounding terrain.

Heat of Vaporization
