Solids, Liquids & Gases Worksheet-5
(A) The particles are far away from each other and they can move freely
(B) The particles are tightly packed in a rigid pattern and they cannot move
(C) The particles are not so tightly packed and they can move
(A) Solid (B) Gaseous (C) Liquid
(A) Evaporation (B) Condensation (C) Expansion
(A) Carbon dioxide (B) Oxygen (C) Nitrogen
(A) Solute (B) Solvent (C) Solution
(A) Evaporation (B) Condensation (C) Heating
(A) Smaller is the surface area of liquid exposed to the heat, faster is the rate of evaporation
(B) Container “C” is flat, evaporation occurs faster in the flat surface as compared to the curved surface
(C) Container “C” is broad, maximum surface area of liquid gets exposed to heat which in turn allows maximum evaporation
(A) CNG (B) LPG (C) Carbon dioxide
(A) Condensation (B) Expansion (C) Evaporation
(A) Diesel (B) Kerosene (C) Water
