Three Types of Thermometers:

  1. Mercury Thermometer: Uses mercury in a glass tube to measure temperature changes based on the expansion and contraction of the liquid.

  2. Digital Thermometer: Uses electronic sensors to provide a digital readout of temperature, often used for quick measurements.

  3. Infrared Thermometer: Measures temperature from a distance by detecting the infrared radiation emitted by an object, commonly used for non-contact measurements.

Freezing Point of Water in Celsius:

The freezing point of water on the Celsius scale is 0 degrees Celsius.

Arranging Temperatures from Coldest to Warmest:

(a) The temperatures to arrange are:
-8 degrees Celsius, -2 degrees Celsius, -1 degrees Celsius, 15 degrees Celsius, 25 degrees Celsius.

Arranged Order:
-8 degrees Celsius, -2 degrees Celsius, -1 degrees Celsius, 15 degrees Celsius, 25 degrees Celsius.

(b) The temperatures to arrange are:
5 degrees Celsius, 38 degrees Celsius, 17 degrees Celsius, 0 degrees Celsius.

Arranged Order:
0 degrees Celsius, 5 degrees Celsius, 17 degrees Celsius, 38 degrees Celsius.
