Question

Consider a sample of water at 0 degrees C. If the temperature is slightly increased, the volume of the water

A) increases

B) decreases

C) remains the same

Answer 1

B) decreases

Step-by-step explanation:

The density of water is maximum at a temperature of
`4^(\circ) C`. This means that:

- For temperatures between 0 and 4 degrees C, as the temperature increases, the density increases

- For temperatures above 4 degrees C, as the temperature increases, the density decreases

The density is related to the volume by the formula:

`d=(m)/(V)`

where m is the mass and V the volume. Therefore, density is inversely proportional to the volume. This means that, for a constant amount of mass:

- For temperatures between 0 and 4 degrees C, as the temperature increases, the volume decreases

- For temperatures above 4 degrees C, as the temperature increases, the volume increases

Therefore, for a sample of water at 0 degrees C, if the temperature is slightly increased, the volume of the water will decreases, because its density will increase.
