It is important to leave a space between the temperature number and the unit to ensure clarity and avoid confusion. For example, instead of writing 25°C without a space, it should be written as 25 °C. This helps in distinguishing ...

The boiling point of water at sea level is 100°C (212°F). This is the temperature at which water changes from a liquid to a gas, or vapor. At sea level, the atmospheric pressure is standard, which allows water to boil ...
The bulb of a thermometer should be completely immersed in the liquid to measure its temperature accurately. It should be placed in such a way that the bulb is fully surrounded by the liquid, ensuring that the temperature of the ...
Room temperature refers to the temperature of the environment in a typical indoor setting, where people feel comfortable. It is usually around 20°C to 25°C (68°F to 77°F). This temperature is neither too hot nor too cold and is considered ...
To convert Celsius (°C) to Kelvin (K), you simply add 273 to the Celsius temperature. The formula is: Kelvin (K) = Celsius (°C) + 273 For example, if the temperature is 25°C, the conversion to Kelvin would be: 25°C + ...
The liquid commonly used in laboratory thermometers is mercury. Mercury expands and contracts evenly with temperature changes, making it ideal for accurate measurements. It is visible in the thermometer because it is a shiny, silver liquid that moves along the ...
After using a thermometer, it should be cleaned carefully to ensure it remains hygienic and accurate. First, wipe the thermometer with a soft cloth or tissue to remove any moisture. Then, use a disinfectant or a mild soap solution to ...
The boiling temperature of water is lower at high-altitude places because the atmospheric pressure is lower than at sea level. At high altitudes, the air pressure is reduced, which means water molecules can escape into the air at a lower ...
The smallest temperature value a thermometer can read is called the least count. It refers to the smallest division or increment on the thermometer’s scale. For example, in a thermometer with a least count of 1°C, it can measure temperature ...
Air temperature is important for weather reports because it helps determine the overall weather conditions, such as whether it will be hot, cold, or moderate. It affects how we feel, what clothes we wear, and how weather phenomena like rain, ...
