Assertion: The density of a liquid depends upon the nature and temperature of the liquid.
Reason: The volume of the liquid depends upon temperature.
Explanation:
The density of a substance is defined as its mass per unit volume. It is a measure of how closely packed the particles of the substance are. The density of a liquid depends on two factors - the nature of the liquid (the type of substance it is made of) and the temperature at which it is measured.
1. Density and Nature of Liquid: Different liquids have different densities because their particles are arranged differently. For example, mercury is a dense liquid compared to water because its particles are more closely packed. The nature of the liquid determines the arrangement and packing of its particles, which affects its density.
2. Density and Temperature: The volume of a liquid is affected by temperature. When a liquid is heated, its particles gain energy and move faster, causing them to spread apart. This leads to an increase in volume. Conversely, when a liquid is cooled, its particles lose energy and move slower, causing them to come closer together. This leads to a decrease in volume.
The density of a liquid remains constant regardless of its volume. However, as the volume of a liquid changes with temperature, the density also changes. When the volume of a liquid increases, its density decreases, and when the volume decreases, its density increases. Therefore, the volume of the liquid does have an effect on its density.
Conclusion:
Both the assertion and the reason are true, and the reason is the correct explanation of the assertion. The density of a liquid depends on its nature and temperature, and the volume of the liquid depends on temperature. The reason explains why the nature and temperature of a liquid affect its density.
