A mixture of iron, salt, and sand can be separated using a magnet, water, a filter, and a hot plate. This separation _____.

Answers

Answer 1

Answer:

i think mixture

Explanation:

sorry if it wrong(tried my best)

Answer 2

Answer:

This is an example of a mixture that can be separated with simple separation techniques based on the physical properties of the mixtures. Magnetism, and filtration and evaporation

Iron is a magnetic material, but salt and sand are not, therefore, the iron can be separated from the mixture with the use of a magnet.

Salt and sand are mixable. Salt is soluble in water, but sand is not. Therefore by adding the sand and salt to water, the salt will dissolve,in the water(solvent) to form a salt solution. But the sand can be separated out of the solution by filtration with the filter paper inserted into a funnel which allows the salt solution to pass through while restricting the sand.

The sand would be removed by the filter paper, while the solution passes through.

The salt solution and some sand residues are placed in an evaporating dish and heated at low temperatures. The water from the solution evaporates, leaving the salt behind.

Boyle’s law states that if the temperature of an ideal gas is held constant, then the pressure p of the gas and its volume v satisfy the relationship p=kv, where k is a constant. Which of the following best describes the relationship between the rate of change, with respect to time t, of the pressure and the rate of change, with respect to time t, of the volume?.

Answers

The best answer that describes the relationship between the rate of change with respect to time of the pressure and the rate of change with respect to time t of the volume is; dP/dt = (-k/V²)(dV/dt)

We are given;

p = k/v

Thus if we cross multiply, we will get;

PV = k

Where;

P is pressure

V is volume

k is a constant

Using the product rule of differentiation on both sides with respect to time t gives;

V(dP/dt) + P(dV/dt) = 0

This is because k is a constant.

Putting k/v for P gives;

V(dP/dt) + (k/V)(dV/dt) = 0

>> V(dP/dt) = - (k/V)(dV/dt)

Divide both sides by V by division property of equality to get;

dP/dt = (-k/V²)(dV/dt)
