The effect on the melting point of a pure substance when another substance is added depends on the nature and quantity of the added substance. Generally, the presence of impurities decreases the melting point of the pure substance.
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 ...
Water’s high specific heat allows it to absorb a significant amount of heat from the engine, effectively cooling it. This property makes water an efficient coolant for radiators in motor vehicles, helping to maintain engine temperatures within safe operating limits.
