Plasma	high-energy state whose atoms are ionized, at least 5% of them. Its intermolecular attractive forces are practically zero and its molecular kinetic energy is very high
Density	is the relationship between the mass of a substance and its volume
Pressure	is the ratio of the applied force to the area where it is applied
n/m2	way to represent pascals (pressure)
1.013x10^5	1 atm=
Open tube manometer	It consists of a transparent U-shaped tube into which a liquid is poured.
Mercury batometer	Designed to measure atmospheric pressure, it consists of a glass tube closed at one end.
Pascals principle	pressure changes at any point in a fluid enclosed and at rest, are transmitted equally to all points of the fluid and act in all directions
Archimedes principle	A body totally or partially submerged in a fluid, experiences a buoyant force equal in magnitude to the weight of the volume of fluid displaced
Temperature	is the variable that determines the state of thermal equilibrium of the systems.
Thermal equilibrium	It is the state that is reached when macroscopic variables such as pressure, volume and temperature do not vary over time.
Temperature	is a measure of the average kinetic energy of the molecules of a substance.
Thermometric properties	They are those properties of substances that present variation in their magnitude when the temperature changes
Celsius	Scale that is the most widely accepted in the world. it is based on the melting and boiling points of water under normal conditions.
Fahrenheit	It was one of the first proposed scales. His reference points are: the temperature of a mixture of water, ice and salt, and the average temperature of the human body.
Kelvin	It is an absolute scale since it measures temperature based on what it physically represents, that is, the average molecular kinetic energy of substances. Its lower limit is the absolute zero of temperatures.
Specific heat	explains why some of them get hotter than others, even though both have received the same amount of heat.
thermodynamics	refers to the study of the transformation of heat into other types of energy, as well as the study of the transformation of other types of energy into heat.
conduction	occurs when energy propagates due to collisions between the particles, so that in each collision the particles give up part of their kinetic energy to the particles with which they interact, all without there being net transport of matter.
convection	there is a transport of energy associated with the displacement of masses of fluid within the fluid itself, due to the differences in density caused by the different temperatures of some areas.
radiation	is the propagation of energy through electromagnetic waves that all bodies emit due to having a temperature above absolute zero. In it energy is transported without matter transport.
