A 30cm3 volume of water was placed in a cylinder, and a stone was dropped in. The water level rose by 35cm3. Is it true that the stone was 5cm3?

The volume of stone is 5cm³.

Explanation:

Given data:

Volume of water = 30 cm³

Volume of water and stone = 35 cm³

Volume of stone was 5 cm³ = true or false

Solution:

To check weather the given volume of stone is true or not we have to calculate the volume of stone from given data.

Volume of stone = (volume of water + stone ) - volume of water

Now we will put the values.

Volume of stone =  35 cm³ - 30 cm³

Volume of stone = 5 cm³

Thus the given value is true. The volume of stone is 5cm³.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
