Collisions between particles transfer thermal energy, without any overall transfer of matter.
What is Conduction
100
Change of phase from liquid to gas that takes place at the surface of a liquid
What is Evaporation
100
The thermal motion of atoms in a substance approaches zero, the kinetic energy of the atoms approaches zero, and the temperature of the substance approaches a lower limit
What is Absolute zero
100
Time of a back-and-forth swing of the pendulum
What is Period
100
A wave reaches a boundary between two media, usually some or all of the wave bounces back into the first medium
What is reflection
200
Heat is transferred by movement of the hotter substance from one place to another
What is Convection
200
Any substance contains the maximum amount of another substance
What is saturated
200
Whenever heat is added to a system, it transforms to an equal amount of some other form of energy
What is first law of thermodynamic
200
The number of vibrations an object makes in a unit of time
What is Frequency
200
The law states that the angle of incidence and the angle of reflection are equal to each other
What is the law of reflection
300
rate of cooling is proportional to the temperature difference between the object and its surrounding
What is newton's law of cooling
300
maximum amount that could be in the air at the same temperature.
What is relative humidity
300
A gas is compressed or expanded so that no heat enters of leaves a system
What is adiabatic
300
The formula is v=λf
What is the formula for wave speed
300
Light is incident on a rough surface, it is reflected in many directions
What is Diffuse reflection
400
The greenhouse effect
What is the effect that the warming of a planet due to the trapping of radiation by the planet's atmosphere called
400
The phenomenon of melting under pressure and freezing again when the pressure is reduced
What is Regelation
400
Heat will never of itself flow from a cold object to a hot object
What is second law of thermodynamics
400
Waves from different sources arrive at the same point at the same time
What is Interference pattern
400
This is caused by the refraction of light in Earth's atmosphere
What is mirage
500
An energy that travels in a mixture of wavelengths.
What is radiant energy
500
A device that moves heat
What is Heat pump
500
T(hot) - T(cold) / T(hot)
What is Ideal/ Carnot efficiency
500
A wave source approaches, an observer encounters waves with a higher frequency. The wave source moves away, an observer encounters waves with a lower frequency
What is Doppler effect
500
Sometimes called light pipe, are transparent fibers that pipe light from one place to another
