Question

When water freezes, its volume increases by 9.05%. What force per unit area is water capable of exerting on a container when it freezes? a)0.20 kPa

b)0.20 MPa
c)0.20 GPa
d)0.20 TPa

Answer 1

The Pressure is 0.20 MPa.

(b) is correct option.

Step-by-step explanation:

Given that,

Change in volume = 9.05%

{tex]\dfrac{\Delta V}{V_{0}}=0.0905[/tex]

We know that.

The bulk modulus for water

`B=0.20*10^(10)\ N/m^2`

We need to calculate the pressure difference

Using formula bulk modulus formula

`B=\Delta P(V_(0))/(\Delta V)`

`\Delta P=B(\Delta V)/(V_(0))`

`\Delta P=0.2*10^(10)*0.0905`

`\Delta P=0.2*10^(6)\ Pa`

`\Delta P=0.20 MPa`

Hence, The Pressure is 0.20 MPa.
