⚠️ Common Exam Traps & Conceptual Pitfalls

Students frequently reverse the cause‑effect relationship, assuming that supplying heat to a body means doing mechanical work on it. Remember that heat and work are both ways of transferring energy; doing work on a system can raise its internal energy and thus its temperature, but providing heat does not imply work is being done.

Heat and work are equivalent. This means, ____________.

Multiple Choice Options

  • A when we supply heat to a body we do work on it
  • B when we do work on a body we supply heat to it
  • C the temperature of a body can be increased by doing work on it
  • D a body kept at rest may be set into motion along a line by supplying heat to it

Step-by-Step Verified Solution

**Answer:** (c) the temperature of a body can be increased by doing work on it. **Step-by-Step Explanation:** Heat and work are equivalent forms of energy transfer. Doing work on a body can increase its temperature.
