The emitted or absorbed heat which changes the state of the substance but does not cause any change in temperature is called latent heat. This energy is used for phase transitions, such as melting or boiling, without altering the substance’s ...

Water on mountains starts boiling at a temperature less than 100°C due to the lower atmospheric pressure at higher altitudes. The reduced pressure decreases the boiling point of water, causing it to boil at temperatures below 100°C.
Due to impurities, the boiling point (B.P) of a liquid increases. This phenomenon is known as boiling point elevation and is a colligative property. The presence of impurities lowers the vapor pressure of the solution, requiring a higher temperature for ...
Mercury is generally used in thermometers because it has high density. Its high density allows for precise and easily readable measurements due to the small size of the thermometer’s scale. Additionally, mercury’s low freezing point and wide liquid range make ...
The point at which the Fahrenheit temperature is double the Celsius temperature is -40 °F. At this temperature, -40 °F is equal to -40 °C.
