4. How does adding salt in a solution of water (salinity) affect the density of the water and how it mixes with freshwater added to it? Make sure you explain how the experiment helps you answer this question.

I think it can be solved using a spring balance (which is used to measure the upward force of a liquid)

Take a beaker and fill it with water. Using a spring balance measure Its upward force or buoyant force. Write down. Now repeat it this time using salt solution. The buoyancy or upward force must be higher in this case. As solute is added to a solvent it makes it much more denser. According to Archimedes's Principle : when an object is partially or fully immersed in a liquid the upward force experienced by it is directly proportional to the weight of the water it displaces. In the salt solution which is denser it displaces more water thus creating a stronger force.

I hope it helps. Thank you

hi there!

answer: b. nucleolus

explanation: nucleolus is a structure in the nucleus are ribosomes are made.

hope this you!

have a nice day! : )

: d

you! : )

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
