The most suitable thermometer for measuring the boiling point of water is?

A. Alcohol Thermometer
B. Mercury Thermometer
C. Liquid Crystal Thermometer
D. Bimetallic Thermometer

Answer

Correct Answer: B. Mercury Thermometer

Detail about MCQs

The most suitable thermometer for measuring the boiling point of water is a mercury thermometer. Mercury thermometers are commonly used for measuring temperatures within the range of –38°C to 356°C (-36°F to 672°F), making them ideal for measuring the boiling point of water, which is typically around 100°C (212°F) at standard atmospheric pressure. Mercury thermometers provide accurate and reliable readings within this temperature range

The speed of sound in dry air at 20C is about?

A. 343 m/s
B. 230 m/s
C. 130 m/s
D. 430 m/s

Answer

Correct Answer: A. 343 m/s

Detail about MCQs

The speed of sound in dry air at 20°C is approximately 343 meters per second (m/s). This value is affected by factors such as temperature, pressure, and humidity. In dry air at standard conditions, sound travels at this speed, which is commonly used as a reference value in physics and engineering calculations involving sound propagation
