What temperature scale never shows negative values?

The Kelvin (K) scale is the absolute temperature scale, where 0 K represents absolute zero. Temperatures on this scale are always non-negative.

How does thermal expansion affect materials?

Thermal expansion is the tendency of matter to change its volume in response to temperature changes. Most substances expand when heated and contract when cooled. This is a critical concept for ENGINEERING 2026.

What is the principle behind 'good emitters are good absorbers'?

This is Kirchhoff's Law of Thermal Radiation, stating that for an object in thermal equilibrium with its surroundings, its emissivity is equal to its absorptivity at the same temperature and wavelength. It's a fundamental principle for the ENGINEERING 2026 syllabus.

Will an electric fan cool a closed room?

An electric fan does not cool the air in a closed room; it only circulates the existing air. While it might create a sensation of cooling due to increased evaporation from the skin, the room's actual temperature remains unchanged or slightly increases due to the fan's motor heat. This is a common point of confusion for ENGINEERING 2026 aspirants.

What is specific heat capacity?

Specific heat capacity is the amount of heat energy required to raise the temperature of one unit of mass of a substance by one degree Celsius (or Kelvin). Understanding this is vital for ENGINEERING 2026 physics.

What are anisotropic substances in terms of thermal expansion?

Anisotropic substances have different physical properties in different directions. For thermal expansion, this means their coefficient of linear thermal expansion varies with direction, unlike isotropic substances where it's the same in all directions.

What is the significance of the 2026 exam year for these MCQs?

These MCQs are tailored to help students preparing for the ENGINEERING 2026 examinations. The topics and difficulty level are aligned with typical syllabus requirements and exam patterns expected for 2026, providing targeted practice.
