The table below shows the shapes of two samples, c and d, when placed in three containers of different shapes. shape of sample shape of container shape of sample c shape of sample d cylindrical cylindrical cube spherical spherical cube cube cube cube which of the following correctly describes the state of matter of one of the samples? d is a liquid because it retains its shape. d is a solid because it retains its shape. c is a liquid because it has a definite volume. c is a solid because it has an indefinite volume.

The answer is B,

"D is a solid because it retains it's shape."

Option (b) is the correct answer.

Explanation:

In a solid, molecules are held together by strong intermolecular forces of attraction. As a result, they are unable to move from their initial place but they can vibrate at their mean position.  

Hence, in solid substances the molecules have low kinetic energy.

Whereas in liquids, the molecules are held by less strong intermolecular forces of attraction as compared to solids. Due to which they are able to slide past each other. Hence, they have high kinetic energy as compared to molecules of a solid.

Therefore, as sample D is retaining its shape so, it is a solid.

Thus, we can conclude that the statement D is a solid because it retains its shape correctly describes the state of matter of one of the samples.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
