What is the freezing point of water in Celsius?
100°C
32°C
0°C
-273°C
Celsius, a unit of temperature measurement in the International System of Units (SI), is widely used in scientific and everyday contexts. It is based on the properties of materials and their responses to heat, a fundamental concept in physics. Celsius scale measures temperature through the degree Celsius (°C), where water freezes at 0°C and boils at 100°C at standard atmospheric pressure. Temperature, a measure of the average kinetic energy of particles in a substance, affects various processes including conduction and radiation, which are modes of heat transfer crucial in understanding thermal dynamics.
Where:
Absolute zero in Celsius is the lowest possible temperature that can theoretically be reached, where all molecular motion ceases. It is defined as 0 Kelvin (0 K), which is equivalent to approximately -273.15 degrees Celsius (°C). At this temperature, atoms and molecules have minimal energy and do not move, resulting in a complete absence of thermal energy. Absolute zero serves as the basis for the Kelvin temperature scale and is a fundamental concept in thermodynamics and physics.
To convert Fahrenheit (°F) to Celsius (°C), you can use the following formula:
C = 1.8(F−32)
Where:
Here’s a step-by-step guide:
Let’s illustrate this with an example:
Suppose you have a temperature of 68 degrees Fahrenheit (°F), and you want to convert it to Celsius (°C).
C = 1.8(68−32)
C = 1.836
C = 20
So, 68°F is equivalent to 20°C.
Temperature Scale | Freezing Point of Water | Boiling Point of Water | Absolute Zero |
---|---|---|---|
Fahrenheit (°F) | 32°F | 212°F | -459.67°F |
Celsius (°C) | 0°C | 100°C | -273.15°C |
Negative temperatures on the Celsius scale indicate temperatures below freezing, which are common in colder climates and during winter months.
0°C represents the freezing point of water, and 100°C represents the boiling point of water at standard atmospheric pressure. These reference points make the Celsius scale easy to understand and use.
Celsius is more commonly used in scientific and international contexts, while Fahrenheit is still prevalent in some regions, particularly the United States
