It snows on high hills because the temperature is lower than the freezing point, causing water vapor to freeze and turn into ice. As air rises over the hills, it cools, and if the temperature drops below freezing, the water ...

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 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.
Dew is not formed on a strong windy night because the rate of evaporation is fast. The movement of air removes the thin layer of moisture near the ground, preventing dew formation.
With an increase in pressure, the boiling point of a liquid typically increases. This is because higher pressure increases the kinetic energy required for liquid molecules to escape into the vapor phase, thus necessitating a higher temperature to achieve the ...
Boiling is the process where a substance changes from its liquid state to vapor state throughout the bulk of the liquid, typically occurring at a specific temperature called the boiling point.
Water has the highest specific heat value among the options provided. Its specific heat capacity is approximately 4.18 J/g °C, significantly higher than that of glass, copper, or lead. This property makes water an excellent substance for storing and regulating ...
The specific heat capacity of water is very high. Water’s high specific heat capacity allows it to absorb and store more heat energy compared to land. As a result, land heats up faster during the day than sea water, contributing ...
Specific heat refers to the amount of heat required to raise the temperature of one unit mass of a substance by one degree Celsius. It is a characteristic property of the substance and is measured in units of energy per ...
The walls of a thermos flask are galvanized with a reflective coating to minimize heat transfer by radiation. This shiny coating reflects infrared radiation, reducing heat loss and maintaining the temperature of the contents.
