Physical and Chemical Properties — Predicted 2026

AI-Predicted Question Angles for UPSC 2026

Based on trend analysis, current affairs, and recurring themes in Physical and Chemical Properties.

Identification of Intensive vs. Extensive Properties in a novel context.

high

This distinction is a classic conceptual test. NEET often presents a list of properties and asks to identify the intensive or extensive one. A slightly harder variant might involve a scenario where a property is described, and the student must infer its type. For example, 'A substance has a specific heat capacity of X J/g°C. Is specific heat capacity an intensive or extensive property?' This tests application of the definition beyond simple recall.

Differentiating Physical vs. Chemical Changes based on observable indicators.

high

Questions asking to classify a process as physical or chemical change are very common. The predicted angle is to provide a description of a process with multiple observable changes (e.g., 'When substance A is heated, it melts, then boils, and finally burns with a flame, producing a gas and a black residue.') and ask to identify which part of the process represents a chemical change. This requires careful analysis of multiple steps and their associated indicators.

Application of properties in separation techniques.

medium

While separation techniques (like distillation, filtration, chromatography) are physical processes, their effectiveness relies on differences in physical properties (boiling point, solubility, particle size). A question could link a separation technique to the specific physical property it exploits. For example, 'Which physical property is primarily utilized in the process of distillation to separate components of a liquid mixture?' This tests the practical application of understanding physical properties.
