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.

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.
When salt is added to water, the boiling point increases and the freezing point decreases. This phenomenon is due to the colligative properties of solutions, where the presence of a solute affects the boiling and freezing points of the solvent.
In an adiabatic change, no heat is exchanged with the surroundings, so heat remains unchanged. However, the temperature of the system can change due to work done on or by the system.
The rate of evaporation for a certain liquid depends on all the above factors. It depends on the temperature of the liquid, the temperature of the air, and the open surface area of the liquid.
It will take more time to cook rice on Mount Everest due to the lower atmospheric pressure at high altitudes, which lowers the boiling point of water. This means water boils at a temperature below 100°C, slowing the cooking process.
The rate of evaporation does not depend on the total volume of the liquid. Evaporation primarily depends on factors such as temperature, surface area, and air pressure. The volume of the liquid does not directly influence the rate at which ...
The temperature at which ice, water, and vapor coexist in equilibrium is called the triple point. This is a unique thermodynamic state where all three phases are present simultaneously.
Due to the evaporation of a liquid, its temperature will decrease. This occurs because evaporation is an endothermic process, where the liquid absorbs heat from its surroundings to transition into a gas, thereby lowering the liquid’s temperature.
The triple point of water is the specific condition at which water can coexist in solid, liquid, and vapor phases. It occurs at a temperature of 273.16 K and a pressure of 611.657 pascals.
