Q1. 1.26 × 10⁵ J of heat is given to 1 kg of water (c = 4200 J kg⁻¹ K⁻¹). The rise in temperature is:
- 30 °C
- 15 °C
- 60 °C
- 300 °C
Show the answer
Answer: A. 30 °C
ΔT = Q/(mc) = 1.26 × 10⁵/(1×4200) = 30 °C.
Q2. Which of these is NOT mainly an example of convection?
- feeling warmth from a fire across a room
- a land breeze blowing at night
- water at the bottom of a pot rising when heated
- a glider rising on a thermal
Show the answer
Answer: A. feeling warmth from a fire across a room
Feeling warmth from a fire across a room: radiation.
Q3. A person stands 510 m from a cliff. If sound travels at 340 m/s, the echo is heard after:
- 3 s
- 6 s
- 30 s
- 1.5 s
Show the answer
Answer: A. 3 s
The correct answer is “3 s”. t = 2d/v = 2×510/340 = 3 s.
Q4. A ray entering a glass block along the normal:
- passes straight through without bending
- disperses
- is totally reflected
- bends towards the normal
Show the answer
Answer: A. passes straight through without bending
The correct answer is “passes straight through without bending”. i = 0 ⇒ r = 0.
Q5. Electrically, salt water is a/an:
- superconductor
- conductor
- magnet
- insulator
Show the answer
Answer: B. conductor
The correct answer is “conductor”. Salt water: conductor.
Q6. A current of 1 A flows for 60 s. The charge that passes is:
- 0.0167 C
- 120 C
- 30 C
- 60 C
Show the answer
Answer: D. 60 C
The correct answer is “60 C”. Q = It = 60 C.
