Question

When equals of water and of methane gas absorb the same amount

of thermal energy change in temperature of the methan a ter than
the change in temperature of the water. Which property helps to explain this
difference?
a-melting point
b-latent heat of vaporization
c-forces between molecules
d-volume

Answer 1

Option-(C): Forces between molecules.

Step-by-step explanation:

Difference in the inter-molecular forces between the molecules of the water,H₂O and the methane gas,CH₄. As, water molecules are held tightly by the hydrogen bonds between them and these types are bonds are more stronger then the Van-der Wal forces which are found inside the molecules of the methane gas,CH₄. While, if any molecules posses some strong inter-molecular forces between its molecules or particles then the compound will posses the enhanced capacity to retain more energy, and thus the water molecules are able to absorb more heat and then the molecules temperature can be raised well enough. For, the methane gas,CH₄ the molecules can not retain enough heat in themselves which is required for raising the temperature,T of the compounds.

Answer 2

The property helps to explain this difference is forces between molecules.

Option c

Step-by-step explanation:

The exact heat of water is
`75.28 J/ mol K`

The exact heat of methane is
`35.7 J/mol K`

This is due to the polarity and the hydrogen bonding.

It takes more energy to break these bonds than methane, therefore, we would think water to have a higher specific heat due to these active forces.

So this property helps to explain there is differences in forces between molecules.
