At a constant temperature and pressure, liquids retain their volume of matter.
Matter is defined as total mass which occupy in space, all the physical structures are composed of matter, it can be present in three basic states such as solid, liquid, and gas.
The atoms are basic unit of matter and that make up the objects which can be visible and touched every day, the amount of matter in an object can be determined by its mass.
A physical property of matter is an independent of its chemical composition. Density, color, hardness, melting and boiling points, and electrical conductivity are the examples.
Some characteristics like density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature are some properties of matter.

Answer:
Both are right
Explanation:
A constant heat must be supplied for several minutes to soldering gun to overcome the melting point of solder. A butane torch is a type of soldering device powered (energised) by the burning of butane gas to melt and solder common metals
