How does the solubility changes with temperature and pressure for both liquid solvent and solute?

Solubility of the liquid increases with temperature.

Explanation:

The solubility of the liquid increases with increase in the temperature but there is no effect of the pressure on the solubility of a liquid, whereas, the solubility of gases in liquids increases on increasing the pressure above above the surface of the liquid.

On increasing temperature of a liquid solvent the kinetic energy of the particles of the solvent increases which makes particles to move faster which breaks the particles of the solute more rapidly with more energy.

Also the saturation point of a solvent can be increased by increasing the temperature of it which allows to dissolve more solute in the solvent beyond the saturation point.

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
