Q5. Steam burn is more severe than that of boiling water because
Asteam burn is independent of relative humidity
Bsteam possesses greater heat energy per unit mass
Cwater boils at a higher temperature
Dsteam burn is dependent on relative humidity
Correct Answer: B
Steam burns are more severe than boiling water burns because steam possesses greater heat energy per unit mass. When steam condenses on the skin, it releases approximately 2260 kJ/kg of latent heat (in addition to the sensible heat from cooling), whereas boiling water only releases sensible heat as it cools.
Numerical example:
1 kg of steam at 100°C releases ~2260 kJ when condensing + heat from cooling
1 kg of water at 100°C releases only ~420 kJ cooling from 100°C to body temperature
Steam delivers more than 5 times the energy!

Q11. What is the mass of silver deposited when 24,125 C of electricity is passed through a solution of silver salt? [Ag = 108, 1F = 96,500 C]
A43.2 g
B108 g
C54 g
D27 g
Correct Answer: D
Using Faraday's law, mass = (M × Q) / (n × F), where n=1 for Ag⁺ + e⁻ → Ag, Q=24125 C, F=96500 C/mol. Mass = (108 × 24125) / 96500 = 27 g.
