You are on the Titanic and want to find something that will float because you didn't

damaskus [11]

Find volume of pillow

L=78cm

B=55cm

H=25cm

$\\ \bull\tt\longrightarrow V=LBH$

$\\ \bull\tt\longrightarrow V=25(78)(55)$

$\\ \bull\tt\longrightarrow V=107250cm^3$

$\\ \bull\tt\longrightarrow V=10.72m^3$

Now

Mass=5.5kg

$\\ \bull\tt\longrightarrow Density=\dfrac{Mass}{Volume}$

$\\ \bull\tt\longrightarrow Density=\dfrac{5.5}{10.72}$

$\\ \bull\tt\longrightarrow Density=0.5kg/m^3$

Density of water=1000kg/m^3

As it is less than density of water it will float on water

________ are weak bonds that are not strong enough to hold atoms together to form molecules but are strong enough to form bonds

olga_2 [115]

<u>Hydrogen bonds </u>are weak bonds that are not strong enough to hold atoms together to form molecules but are strong enough to form bonds within and around large molecules.

The hydrogen bond is weak bond.

The hydrogen bond is electrostatic force of attraction between hydrogen atom and more electronegative atoms or group ( like Florine , oxygen or nitrogen) which is contently bonded.
The hydrogen bond is occur in polar , contently bond atoms in different molecules.
Example is H-O-H or $NH_{3}$
The positively charged hydrogen side of one water molecule is bond with negatively charged oxygen side of another molecule.
