Substances that become liquefied by heating are typically solids that have a melting point below the heating temperature. Common examples include ice, which turns to water, and metals like iron, which melt at high temperatures. Additionally, certain materials like wax and chocolate also liquefy when heated. This process occurs as the heat energy causes the molecules to move more freely, transitioning from a solid to a liquid state.

How to Separate oxygen from liquefied air?
Oxygen can be separated from liquefied air through a process called fractional distillation. This involves gradually heating the liquefied air to separate its components based on their boiling points. Since oxygen has a lower boiling point than other components in air, it will vaporize and can be collected as a gas while the other components remain liquid.
What happened to the salt after heating?
Salt will just become hotter after heating, it will never melt.
What is liquefied by heat?
Many powders and solids can be melted (liquefied) by heat. For instance, sugar and butter is often melted in cooking.
How are gas liquefied?
You cool it down.
Melting?
Becoming liquefied by heat
What is the definition of the word melt?
to become liquefied by warmth
Does cooking gas contains liquefied petroleum gas?
Yes, cooking gas typically contains liquefied petroleum gas (LPG). LPG is a common fuel source used for cooking and heating in households due to its efficiency and convenience.
How does one become a heating contractor?
You can become a heating contractor if you go to college and you can also go to a heating and plumbing school for training. The fastest way to become a heating contractor is to go to the heating and plumbing school and get certified with a license.

Can gas become liquefied?
Yes - low temperature and/or high pressure are needed, how extreme of either depends on the gas.
LPG heating gases are lighter than air?
Yes, LPG (liquefied petroleum gas) heating gases are heavier than air. When released, they tend to sink and accumulate at low levels, increasing the risk of fire or explosion. Proper ventilation and safety measures should be taken when using LPG for heating.
What are the true of LPG heating gases?
LPG (liquefied petroleum gas) is a mixture of propane and butane that is commonly used as a heating fuel. It burns cleanly and efficiently, producing fewer emissions compared to other fossil fuels. It is also versatile, as it can be used in a variety of applications such as heating homes, cooking, and powering vehicles.
What is difference in LPG and Piped Natural Gas?
LPG (liquefied petroleum gas) is a portable fuel stored in cylinders, while piped natural gas is delivered through underground pipelines to homes and businesses. LPG is typically used for cooking and heating in areas without piped natural gas infrastructure.
What does lpg contain?
LPG (liquefied petroleum gas) primarily contains propane, butane, or a mixture of both. It is a mixture of hydrocarbon gases that are used for heating, cooking, and powering vehicles.
What is the definition of melting?
Melting is when a solid becomes hot and "melts" into a liquid. (wax)
What are the constituents in LPG?
LPG (liquefied petroleum gas) typically consists of propane and butane, which are both hydrocarbon gases. These gases are commonly used as a fuel source for heating, cooking, and vehicles due to their high energy content and clean-burning properties.
What is the compound in lpg gas?
The main compounds found in LPG (liquefied petroleum gas) are propane and butane. These hydrocarbons are gases at room temperature and are commonly used as fuel for heating, cooking, and other applications.
