Question

(v) At 4 °C, the density of water is .......
(a) 10 g/cm3
(b) 4 g/cm
(d) 1 x 104 kg/m2
(C) 4 x 103 kg/m3​

Answer 1

Answer:

Density of water is 1 g/cc or 1000 kg/m^3 at 4 degree C.

Answer 2

Correct Question:

At 4 °C, the density of water is ...

(a) 1 g/cm³

(b) 4 g/cm

(d) 1 x 104 kg/m²

(C) 4 x 103 kg/m³

Solution:

The density of water at 4°C is 1 g/cm³ (option a) or 1000 kg/m³.

Let's see a detailed explanation:

• Density is a physical quantity representing the mass per unit volume of a substance.

$\boxed{density = \dfrac{mass}{volume} }$

• Water is a substance which has variable density is depending upon the temperature.

• Density of water is highest at 4°C, and is equal to 1 g/cm³ or 1000 kg/m³.

• So, while calculating the relative density of any other substance, density of water at a temperature of 4°C is considered.
