A cork has a mass of 3 grams and a volume of 16 cms calculate the density
REY [17]

hey mate here is ur answer

solution

mass{m}=3 gram

             =3/1000

             

volume{v}=16cm

                =16/100

               

density=m/v

           =3/1000÷16/100

           =3/160

            =0.01875kg/m3

Louisa put a bowl of water and a bowl of sand in the sun. She put a thermometer in each bowl. Then she recorded the temperature
Helen [10]

The experiment that was carried out by Louisa goes to show us that different materials heat up at different rates.

<h3>What is the specific heat capacity?</h3>

The term specific heat capacity just goes to show us the amount of heat that must be absorbed before the temperature of an object would rise by 1 K. In this case, we can see that we have been told that the after 30 minutes, the sand had heated more than the water. This simply implies that the energy that the sand and the water absorbed was able to increase the temperature of the sand mush more than it increased the temperature of the water.

Thus we can see that the heat capacity of the sand is much less than the heat capacity of the water since the sand could be able to be heated up much faster than the the water could be heated up.

Match the following. 1. A mixture that does not have a uniform composition and the individual components remain distinct. polar
Ganezh [65]

Answer:

Explanation:

1. A mixture that does not have a uniform composition and the individual components remain distinct.

HETEROGENEOUS

An heterogeous mixture is a mixture with components in different phases.

2. A mixture that does have a uniform composition throughout and is always in the same state.

HOMOGENOUS

Homogenous mixtures have just one phase that is uniform all through.

3. A substance that will not dissolve in a solvent.

INSOLUBLE

When a solute cannot dissolve in a solvent to form a solution, we say it is insoluble.

4. A homogeneous mixture

SOLUTION

Solutions are made up of homogenous mixtures solute and solvent.

5. A molecule with no internal charge variation due to bonding.

NON-POLAR

Even distribution of charges especially between species whose electronegativity difference is 0 would lead to the formation of a non-polar compound. Here,

6. A molecule with an uneven distribution of charge due to unequal sharing of electrons during bonding

POLAR

Unequal sharing of electrons forms a polar compound. The more electronegative attracts the shared electron to itself and there is separation of charges. This leads to polarity.

7. A solution which has dissolved as much solute as it can at a particular temperature.

SATURATED

A saturated solution cannot dissolve more solute beacuse it contains enough solute as it can dissolve at a temperature.

8. A solution which is still able to dissolve solute.

UNSATURATED

An unsaturated solution is able to dissolve more solute.
