Terms
to Avoid in topic Heat and Suggested Alternatives:
1. "Easily":
Reason: This term is subjective and lacks precision.
Alternative: Be specific about what is easy. For
example, "copper conducts heat efficiently" instead of "copper
easily conducts heat".
2. "Good
conductor" or "Bad conductor":
Reason: While not incorrect, these terms are
non-specific.
Alternative: Use "high thermal conductivity"
or "low thermal conductivity" to provide quantitative context.
3. "Hot"
or "Cold";
Reason: These terms are relative and imprecise.
Alternative: Use specific temperatures or describe the
thermal state more precisely, e.g., "at a high temperature of 100°C"//
4. "Heat
goes into" or "Heat comes out" Sec B, Q9(SPM 2017)::
Reason: These phrases are too simplistic and lack
technical detail.
Alternative: Use "heat is transferred to" ,"heat
is conducted away from", "reduce heat
transfer".
5. "Heats
up quickly" or "Cools down slowly", Sec B, Q9(SPM 2017) & Sec C,
Q11(SPM 2022):
Reason: These terms are imprecise without context.
Alternative: Use terms like "has a low
specific heat capacity" or "has a high specific
heat capacity".
6. "Keeps
heat in" or "Lets heat out", Sec C, Q11(SPM 2022):
Reason: These phrases are not technically descriptive.
Alternative: Use "acts as an insulator"
// "acts as a conductor"//poor heat conductor.
7. "Easily
heated" or "Hard to heat":
Reason: These terms are too subjective.
Alternative: Use "low specific heat capacity" or "high specific heat capacity".
8. “Not
easily hot” Sec
C, Q11(SPM 2022):
Reason: These terms are too subjective.
Alternative: Use low thermal conductivity, or slow to absorb heat.
9. More
air in or More air out, Sec
C, Q11(SPM 2022):
Reason: The phrase "more air
in" or "more air out" is vague and does not specify the
mechanism or effectiveness of the air movement.
Alternative: Effective air circulation, Efficient air exchange or Optimal ventilation
Reason:
Rarely used in scientific
literature because of its ambiguity.
Alternative:
Thermal Insulation
Example: "The material provides
excellent thermal insulation, reducing heat transfer."
Alternative: High Thermal Resistivity
Example: "Materials with high thermal resistivity are ideal for minimizing heat transfer."
1. Heat
not trapped
Reason: This
phrase is vague and doesn't specify the mechanism by which heat is managed. It
could imply a general idea that heat is not being retained, but it lacks
detail.
Alternative: efficient
heat dissipation or effective heat escape.
