KELVIN SCALE- a thermodynamic temperature scale based LATENT HEAT- the heat evolved or absorbed by unit mass
upon the efficiencies of ideal heat engines. The zero of the scale (specific latent heat) or unit amount of substance (molar latent
is absolute zero. heat) when it changes phase without change of temperature.
KILOGRAM- is defined in terms of three fundamental physical LAW OF ACCELERATION- is Newton's second law of motion,
constants: The speed of light c, a specific atomic transition which is when a body will accelerate with acceleration
frequency Δν Cs, and the Planck constant h. The formal definition proportional to the force and inversely proportional to the mass
is: The kilogram, symbol kg, is the SI unit of mass. is referred as law of acceleration.
KINETIC ENERGY- the kinetic energy ( KE) of an object is the LAW OF INERTIA - also called Newton ’s first law, postulate in
energy that it possesses due to its motion. physics that, if a body is at rest or moving at a constant speed in
KINETIC FRICTION- is defined as a force that acts between a straight line, it will remain at rest or keep moving in a straight
moving surfaces. A body moving on the surface experiences a line at constant speed unless it is acted upon by a force.
force in the opposite direction of its movement. LENGTH- can be defined as a measurement of the physical
quantity of distance. Many qualitative observations fundamental
KINETIC THEORY- A theory of the thermodynamic behavior of
matter, especially the relationships among pressure, volume, to physics are commonly described using the measurement of
and temperature in gases, based on the dependence of length.
temperature on the kinetic energy of the rapidly moving LIQUID NITROGEN- is nitrogen in a liquid state at low
particles of a substance. temperature (−195.79 °C (77 K; −320 °F) boiling point at sea level).
... It is a colorless, low viscosity liquid that is widely used as a
coolant.
LONGITUDINAL WAVES- are waves in which the displacement
of the medium is in the same direction as, or the opposite
direction to, the direction of propagation of the wave.
