General Science questions with solutions
Which vitamin is synthesised in the human body on exposure to sunlight?
- (A)Vitamin A
- (B)Vitamin K
- (C)Vitamin C
- (D)Vitamin D
Show answer and explanation
Correct answer: (D) Vitamin D
The skin produces Vitamin D when exposed to ultraviolet rays in sunlight; its deficiency causes rickets in children. Hence, 'Vitamin D' is the correct answer among the given options.
What is the SI unit of force?
- (A)Newton
- (B)Joule
- (C)Pascal
- (D)Watt
Show answer and explanation
Correct answer: (A) Newton
The SI unit of force is the newton (N); the joule measures energy, the watt measures power and the pascal measures pressure. Hence, 'Newton' is the correct answer among the given options.
What is the pH value of pure water at 25°C?
- (A)1
- (B)14
- (C)0
- (D)7
Show answer and explanation
Correct answer: (D) 7
Pure water is neutral, with a pH of 7 at 25°C; values below 7 are acidic and values above 7 are basic. Hence, '7' is the correct answer among the given options.
Which instrument is used to measure atmospheric pressure?
- (A)Thermometer
- (B)Anemometer
- (C)Hygrometer
- (D)Barometer
Show answer and explanation
Correct answer: (D) Barometer
A barometer measures atmospheric pressure; a hygrometer measures humidity and an anemometer measures wind speed. Hence, 'Barometer' is the correct answer among the given options.
