Assuming you are referring to only two hydrogen atoms, such as in a sample of hydrogen gas, there is a covalent bond between the hydrogen atoms, as well as a small amount of dispersion forces.
A covalent bond is present in HF. This bond is formed by sharing electrons between the hydrogen and fluorine atoms.
A covalent bond exists between chlorine and hydrogen in a molecule of hydrochloric acid (HCl). In this bond, the electrons are shared between the two atoms.
A polar covalent bond exists between hydrogen and chlorine in hydrogen chloride. This bond is formed by the sharing of electrons between the two atoms, where chlorine is more electronegative than hydrogen, leading to an uneven distribution of charge within the molecule.
The two atoms share their electrons - so it is a covalent bond ie a shared pair.
If a molecule contains two carbon atoms and four hydrogen atoms, you can conclude that the two carbon atoms are likely bonded together by a single covalent bond. This kind of bond would allow each carbon atom to have a full outer electron shell and satisfy the octet rule.

Electrons in nonpolar covalent bonds are shared equally between the atoms involved. Covalent bonds between atoms of the same element display this kind of bond. However, bonds between atoms of different atoms can be nonpolar as well. Such bonds include the covalent bond between carbon and hydrogen.
Hydrochloric acid is a covalent bond, as it is formed between non-metal atoms (hydrogen and chlorine) by sharing electrons.
Hydrogen and chlorine form a covalent bond when they combine to make hydrogen chloride (HCl). In this type of bond, electrons are shared between the two atoms to achieve a stable electron configuration.
Hydrogen sulfide typically forms a polar covalent bond, where electrons are shared unevenly between the hydrogen and sulfur atoms. This results in a molecule with a bent shape due to the lone pairs on the sulfur atom.
They both make it hot in a sense, because it is the bond between the carbon and hydrogen that generates heat. When the bond between two atoms is broken, it releases lots of energy, that's why any kind of exothermic reaction produces heat.
In a water molecule, oxygen (which is a quite more electronegative than hydrogen), tends to attract electrons close to it, so it gets a residual negative charge, while hydrogen gets positively charged.That's the reason why water has a high boiling temperature, because water molecules establish electrostatic bonds, between the oxygen and hydrogen from different molecules, creating a kind of net of interactions, which make it harder to evaporate it.
