Question

The density of water at 20°C is 998 kg/m3 and
40°C 992 kg/m3. The coefficient of volume
expansion of water is
(1) 10-410
(2) 3 x 10-41°C
(3) 2 x 10-41°C (4) 6 x 10-41°C​

⭐Actually Welcome to the Concept of the Thermal Expansion

Since we know that,

⭐Gamma = 3 alpha

V° = V(1+¥∆T)

⭐¥=gamma and T= temperature

so we get as

⭐¥= 3 *10^-4
