Answer: Methane on the other hand, is made of
one carbon atom and 4 hydrogen atoms
. Like water, the bonds are covalent. Because water displays hydrogen bonding with other molecules, a large amount of heat energy is required to break this, and water’s boiling point is around 100 degrees celsius.
Why is water a liquid and methane a gas?
Question: Why is water (H2O H 2 O ) a liquid at room temperature while methane (CH4 C H 4 ) is a gas? (a)
Water forms hydrogen bonds and methane only form dispersion forces
. (b) Water forms dispersion forces and methane forms hydrogen bonds.
Does liquid methane contain water?
It is the first world we’ve found so far that has liquid on its surface like Earth does. But there is one major difference;
the liquid is not water, it
is liquid methane/ethane. With temperatures far colder than anywhere on Earth at –179 degrees Celsius, water cannot exist as a liquid, it is frozen as hard as rock.
Is liquid methane a good solvent?
First, it’s
an efficient solvent for biological chemistry
, allowing molecules to move around in cells, and it has properties that are friendly to life — a high heat capacity, the ability to remain in liquid form across a wide temperature range and a molecular density that forces molecules to organize themselves, rather …
What might this do to the cohesion of water molecules compared to methane molecules?
The strong bonds in the hydrogen bonds require more energy to break, causing a higher melting and boiling point.
Water molecules will have greater cohesion between molecules
. … Methane would not take as much heat away as water when it evaporated because it has a low specific heat capacity.
Is liquid methane safe to drink?
Methane is non-toxic
, but it is explosive. And, at very high concentrations, it can cause death by asphyxiation (since there isn’t enough oxygen to get to your lungs). In the chart, the worst sample had 70 mg of methane per liter of drinking water. … So, 106 grams of methane escapes into the air.
Can humans swim in liquid methane?
If you could find a cliff to jump off, it would take you quite a while to float down to the surface of the liquid. … The density of liquid methane is much, much lower than water, so you wouldn’t be as buoyant. Swimming on Earth is easy because
humans aren’t as dense
as water.
Is water stronger than methane?
Water has a higher boiling point because the hydrogen bonds that form among water molecules
are stronger than the Van der Waals interactions among methane molecules
, thus more energy must be provided in order to break the hydrogen bonds and allow the water molecules to escape the liquid state.
Why is water a liquid at room temperature instead of gas?
Water forms a liquid instead of a gas
because oxygen is more electronegative than the surrounding elements, with the exception of fluorine
. Oxygen attracts electrons much more strongly than does hydrogen, resulting in a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom.
Why is water liquid at room temperature but oxygen is a gas?
Water molecules are strongly attracted to each other
, so they remain condensed (that is, a liquid, and not a gas) at higher temperatures. Dihydrogen and dioxygen have no strong attractive forces to hold the molecules together, so they exist as gases at room temperature and pressure (that is, in our everyday lives).
Can anything live on Titan?
Although
there is so far no evidence of life on Titan
, its complex chemistry and unique environments are certain to make it a destination for continued exploration.
Do other planets have methane?
Methane (CH
4
) is abundant on the giant planets—
Jupiter, Saturn, Uranus and Neptune
—where it was the product of chemical processing of primordial solar nebula material.
Does Methyne exist?
Alkynes have a carbon to carbon triple bond. C
n
H
2n – 2
is their general formula.
“Methyne” does not exist because of methane’s one carbon atom
.
Why does water have a higher heat capacity than methane?
When a water molecule evaporates, hydrogen bonds between it and other molecules must be broken. … Explanation = Water’s heat capacity is higher;
hydrogen bonds restrict movement so more energy is stored by moving molecules of water than methane
.
What gives water its cohesive properties?
Water is highly cohesive—it is the highest of the non-metallic liquids. … More precisely, the
positive and negative charges of the hydrogen and oxygen atoms
that make up water molecules makes them attracted to each other.
What is one difference between methane and water?
Differences between Water and Methane
Water is polar and can form intermolecular hydrogen bonds
(due to high electronegativity of oxygen atom) Methane is non-polar and can only form weak dispersion forces between its molecules (carbon has a lower electronegativity)
