IDENTIFICATION Flashcards
It is a measure of how hot or cold something is, a measure of that average kinetic energy of the particles in a system
TEMPERATURE
Also known as thermometry, describes the process of measuring a current local temp for immediate or later evaluation.
TEMPERATURE MEASUREMENT
Minimum temperature known
ABSOLUTE ZERO
The process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material
CONDUCTION
The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise , and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
CONVECTION
The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
RADIATION
Most versions have used mercury as the liquid.
LIQUID GLASS THERMOMETER
Bonding two dissimilar metals with different coefficients of expansion produces a bimetallic element.
BIMETALLIC THERMOMETER
It is an assembly of two wires of unlike metals joined at one end designated the hot end. At the other end, referred to as the cold junction, the open circuit voltage is measured.
THERMOCOUPLE
It is a temp sensor which measures temp using the principle that the resistance of a metal changes with temperature.
RESISTANCE TEMPERATURE DETECTOR
It is also a resistive device that changes its resistance predictably with temperature.
THERMISTOR
They are non-contact temp sensors that measure temp from the amount of thermal electromagnetic radiation received from a spot on the object of measurement.
PYROMETER
Itbis defined as a ratio between a force and a unit area, perpendicular to the direction of that force on which the force acts.
PRESSURE
Also referred as “hydrostatic pressure” is the pressure of a fluid at rest.
STATIC PRESSURE
The pressure of a fluid moving.
DYNAMIC PRESSURE
