HCL has a low m.p because of the covalent bond which is weaker as compared to ionic bonds. So low amount of heat is needed in order to break these bonds and hence the mp is low
hydrogen is a gas consequently doesn't have a melting point. You can't melt oxygen can you. -------------------------------------------------------------------------------------------------------- Actually oxygen can freeze and melt: its melting point is -361.8°F (-218.8°C). Even hydrogen can freeze and melt: its melting point is -434.49 °F(−259.16°C) These are very cold temperatures!
Yes salts have a low melting point. I think...
it has a low melting point
This substance is likely an ionic solid, as they tend to have low melting points and are usually soft. Examples include salts like sodium chloride.
Yes, gallium has a relatively low melting point of 29.76°C (85.57°F), which allows it to melt in the palm of your hand. This low melting point makes it a unique element with various applications in fields such as electronics and medicine.

Hydrogen fluoride has a low melting point due to its weak intermolecular forces. The hydrogen bonding in HF molecules is relatively weak, leading to lower melting and boiling points compared to substances with stronger intermolecular forces.
Iodine, at p=p0,Boiling point 457.4 K,  184.3 °C(So I don't know if you'd call this high or low? compared with what?)However the difference with melting point of Iodine (386.85 K,  113.7 °C) is remarkably small (< 71oC) and the solid is quite vaporous far below its boiling point (Triple point 386.65K (113.5oC), 12.07 kPa, just below melting point).
sodium chloride melt earlier because it has low freezing point
One example of a compound with both ionic and covalent character is ammonium chloride (NH4Cl). It has a low melting point due to its ionic interactions between ammonium cations and chloride anions and covalent interactions within the ammonium ion itself.
Naphthalene has a relatively low melting point of around 80 degrees Celsius.
Yes salts have a low melting point. I think...
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
It has a melting point of 113 degrees celieus
Yes it solidifies into ice at very low temperatures below about 150 K and low pressures.
low resistivity and low melting point.
Chlorine has a low melting point of -100.98°C and a low boiling point of -34.6°C.
