A measure of how hot or cold something is referred to as temperature. Temperature is a quantitative measure that indicates the degree of heat present or the intensity of coldness in an object or a system.
To measure temperature, we typically use a thermometer. Most thermometers contain a temperature-sensitive material, such as mercury or alcohol, which expands or contracts in response to temperature changes. By observing the level of expansion or contraction, we can determine the temperature of the object being measured.
There are different scales used to measure temperature, including Celsius (°C), Fahrenheit (°F), and Kelvin (K). Celsius is commonly used in scientific and everyday contexts, whereas Fahrenheit is primarily used in the United States and a few other countries. Kelvin is an absolute scale often used in scientific and engineering applications.
