Physical property

Dissolve

Explanation:

A physical property of salt is that it will dissolve in water.

A salt is an ionic compound consisting of positive ions such as metallic, ammonium and complex ions and negative ions such as acid radicals and complex ions.

The physical property of substance tells us everything about a substance when no change is occurring to its constituents.

Solubility is an example of physical property of matter.
Generally, like substances will dissolve one another.
Salt is an ionic compound, and like water, it is polar.
Water molecules will aggregate round each salt particle and hydrate them into solution.

FinnZ [79.3K]

Answer:

Explanation:

If a car is moving to the left with constant velocity, one can conclude that

there must be no forces applied to the car . The net force applied to the car is zero.

Since there is no acceleration ,no net force is applied , hence no force acts on the car.

A natural water molecule (H2O) in its vapor state has an electric dipole moment of magnitude, p = 6.2 x 10-30 C.m. (a) Find the

Vika [28.1K]

Answer:

a $D = 3.9 *10^{-12} \ m$

b $\tau_{max} = 1.24 *10^{-25} \ N\cdot m$

c $W = 2.48 *10^{-25} J$

Explanation:

From the question we are told that

The magnitude of electric dipole moment is $\sigma = 6.2 *10^{-30} \ C \cdot m$

The electric field is $E = 2*10^{4} \ N/C$

The distance between the positive and negative charge center is mathematically evaluated as

$D = \frac{\sigma }{10 e}$

Where e is the charge on one electron which has a constant value of $e = 1.60 *10^{-19} \ C$

Substituting values

$D = \frac{6.20 *10^{-30}}{10 * (1.60 *10^{-19})}$

$D = 3.9 *10^{-12} \ m$

The maximum torque is mathematically represented as

$\tau_{max} = \sigma * E * sin (\theta)$

Here $\theta = 90^o$

This because at maximum the molecule is perpendicular to the field

substituting values

$\tau_{max} = 6.2 *10^{-30} * 2*10^{4} sin ( 90)$

$\tau_{max} = 1.24 *10^{-25} \ N\cdot m$

The workdone is mathematically represented as

$W = V_{(180)} - V_{0}$

where $V_{(180)}$ is the potential energy at 180° which is mathematically evaluated as

$V_{(180) } = - \sigma * E cos (180)$

Where the negative signifies that it is acting against the field

substituting values

$V_{(180) } = - 6.20 *10^{-30} * 2.0 *10^{4} cos (180)$

$V_{(180) } = 1.24*10^{-25} J$

and

$V_{(0)}$ is the potential energy at 0° which is mathematically evaluated as

$V_{(0) } = - \sigma * E cos (0)$

substituting values

$V_{(0) } = - 6.20 *10^{-30} * 2.0 *10^{4} cos (0)$

$V_{(0) } =- 1.24*10^{-25} J$

So $W = 1.24 *10^{-25} - [-1.24 *10^{-25}]$

$W = 2.48 *10^{-25} J$
