When heat is added or subtracted, it chemically changes the substance into a different type of matter.
No, nitrogen, whether solid, liquid, or gas, is relatively inert.
A non-liquid substance is a material that is not in a liquid state, such as a solid or a gas.

A gas or a liquid.
Liquid nitrogen is a pure substance because it consists of only nitrogen molecules in liquid form.
the melting point
Any addition of thermal energy to a saturated liquid will cause it to vaporize. Any subtraction of thermal energy from a saturated vapor will cause it to condense.
The density of a substance determines whether it will sink or float in a particular liquid. If the substance's density is greater than the liquid's density, it will sink. If the substance's density is less than the liquid's density, it will float.
A physical state of a substance is whether it is solid, liquid, or gas.
Liquid and gas are considered physical properties because they describe the state of matter of a substance. Physical properties are characteristics of a substance that can be observed or measured without changing the substance's composition, and whether a substance is in a liquid or gas state is one such observable property.
The addition of heat or reduction in pressure can cause a substance to change from either a solid (sublimation) or liquid (evaporation) into a gas.
No, nitrogen, whether solid, liquid, or gas, is relatively inert.
The distance between particles
The two factors that determine the state of a substance are temperature and pressure. These factors influence whether a substance exists as a solid, liquid, or gas.
the addition or giving-up of heat - is required.
A liquid is a substance or a mixture of substances in solution.
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
