Warm water<span> has more energy than cold </span>water, which means that molecules in warm water<span> move </span>faster<span> than molecules in cold </span>water<span>. The </span>food coloring<span> you add to the </span>water<span> is pushed around by the </span>water<span> molecules.

Number of mole s of H
2
= 0.25 moles
number of molecules = moles * Avogadro’s Number
number of molecules = 0.25×(6.022×10
23
)
number of molecules = 1.505×10
23
single molecule of hydrogen contains two H-atoms. So,
number of atoms = 2×(1.505×10
23
) = 3.01×10
23
