Many powders and solids can be melted (liquefied) by heat. For instance, sugar and butter is often melted in cooking.
Becoming liquefied by heat
A sphere has the lowest surface to volume ratio of any solid body. Since liquefied natural gas must be kept at a temperature far below ambient temperature, and since heat can enter the storage container only through its surface, using a spherical container minimizes the energy that must be expended to maintain the stored liquefied natural gas at a low temperature.
by fractional distillation of liquefied air oxygen is obtained due to it's boiling point
lowering the temperature
You cool it down.
Becoming liquefied by heat
answer; to heat homes, to make nitrate fertilizer.
Liquefied petroleum gas is a source of heat we use now. If you're asking for a natural source, its obvious; the sun.
Melting is when a solid becomes hot and "melts" into a liquid. (wax)
Yes. I am not a doctor or pharmacist. I believe they do because heat will allow your skin to become more absorbent. Also, the medication becomes more ply-able and liquefied.
because that's what it is?Liquefied Petroleum Gas = LPG
Natural gas can only be liquefied under extreme pressure.
by compressing it

Helium.
Yes.
