During the electrolysis of acidified water, the volume ratio of hydrogen to oxygen collected is: MCQ with Answer and Explanation

Explanation:
Amorphous solids like glass do not have a sharp melting point; they soften over a range of temperatures. Crystalline solids have sharp melting points and long-range order. Glass is an insulator.

Explanation:
Gamma rays (γ) are high-energy electromagnetic radiation (photons). Unlike alpha particles (mass, +2 charge) and beta particles (mass, -1 charge), gamma rays have zero rest mass and no electrical charge. Thus, they are not deflected by electric or magnetic fields.

Explanation:
Gay-Lussac's law states that at constant volume, the pressure of a fixed mass of gas is directly proportional to its absolute temperature. P ∝ T, so P/T = constant. This is used in pressure cookers and autoclaves.
