when natural gas heats water, what energy conversion is taking place
chemical energy to thermal energy
heat is transferred from one particle of matter to another without the movement of matter itself in a process called
heat transfer occurs from cold objects to warmer ones or from warm objects to cold ones
warm objects to cold ones
the amount of energy required to raise the temperature of 1 kilogram of a substance by 1 kelvin is called its
The addition or loss of thermal energy changes the arrangement of the particles during
a change of state
Which of the following is true of the Celsius scale? 0 degrees is absolute zore, 0 degrees is the freezing point ofwter, 32 degreethe freezing point of water.
0 degrees is the freezing point of water
a measure of the average kinetic energy of the individual particles in an object is called
A solid is a state of matter that has a indefinite or definite shape? definite or indefinite volume?
definite shape and volume
Particles of a liquid do or do not have close contact with each other and are or are not tightly packed?
they are in close contact with one another but are not tightly packed.
Soup is being heated on a stove, and water droplets are forming on the back of the stove. what sequence has occurred?
vaporization then condensation
in cold climates, the amount of snow on the ground may decrease even if the temperature stays below zero degrees Celsius. The process that best describes this event is
during the convection lab, why did the food coloring placed above the cup with hot water rise to the top?
warm water was less dense
What is the movement of the warm and cold fluid called when it develops the "circular" motion?
In the radiation lab activity, what was the dependent variable?
the temperature change of each substance
One possible cause of tectonic plate motion is the rise of hot material from deep within the Earth while cooler material near the surface sinks. As this process repeats, it is an example of
A measure of the average kinetic energy of the individual particles in an object is called
Which of the following surfaces would absorb heat most rapidly? shiny black, shiny white, dull black, dull white, shiny black
Which of the following temperatures is the highest? 100 degrees C, 100 degrees K, 100 degrees F, or they are all the same?
100 degrees C
During conduction heat is transferred by the movement of currents within a fluid.
false, that is convection
Particles of matter in the solid state are held together but can move around each other.
false, they cannot move around each other
A change in the thermal energy of an object is related to the objects specific heat, temperature change, and mass.
