Class 7 Science — Heat Important Questions with Answers (Long answers)
Class 7 Science is the first full year photosynthesis, acids-bases and electric current share one textbook. The rationalized NCERT dropped a few older chapters; what remains is the set CBSE still samples in periodic tests. This hub writes one unique paragraph and a question cluster per surviving chapter so “nutrition in plants class 7 important questions” and “heat class 7 MCQ” resolve to real practice, not an empty subject shell. Answers stay behind a tap. Hindi and English stems sit together because most school papers are bilingual.
Heat flows from hotter to colder until temperatures meet. Conduction needs a material; convection needs a fluid; radiation does not need air — that triad is the whole chapter. Clinical thermometer and laboratory thermometer are not interchangeable: range and kink differ. Land and sea breeze are convection in disguise. Dark surfaces absorb better; that is why a black road feels hotter. Numericals stay at reading a scale, not Class 11 specific heat. You are on Heat (Long answers), page 1 of 1 — 2 questions in this filter. Long answers model a five-mark write-up: definition, reason, one diagram or equation idea, and a closing line. Do not copy the whole block in the exam; steal the order. This view is for the night before a unit test. Phone layout: chapter chips scroll sideways, answers stay inside a tap, and the next page is a numbered link so Google and students both get a short URL. Updated for 2026 classroom practice on the rationalized NCERT.
