Students are investigating temperature changes on substances in their gaseous state. Which of the following is most likely to happen to the gaseous substance when the students decrease the temperature?
molecular motion of the atoms will increase, causing it to change to a solid state
molecular motion of the atoms will decrease, causing it to change to a liquid state
molecular motion of the atoms will decrease, causing it to lose molecular mass
molecular motion of the atoms will increase, causing it to change from the gaseous state
Temperature is the measurement of the average energy of motion of the particles in a substance. Because of this, one could conclude that substances that have had an increase in temperature have USUALLY
undergone a chemical change.
changed into a solid state.
changed into a liquid or gaseous state.
decreased in molecular weight.
The table shows the affect of temperature change on three different substances. From the observations in the table above, one could conclude that increases in temperatures change
liquids to solids and liquids to gases.
solids to liquids and liquids to gases.
liquids to solids and gases to liquids.
solids to liquids and gases to liquids.
An unknown substance changes states when heat energy is added or removed. From this information, one can conclude that temperature changes affect the
chemical state of the substance.
physical state of the substance.
atomic state of the substance.
molecular state of the substance.
After observing many different investigations on the state changes of substances, one could conclude that most substances that change from a gaseous state to a liquid or solid state have had a(n)
increase in molecular weight.
decrease in molecular weight.
increase in temperature.
decrease in temperature.
Use the diagram to answer the following quetion(s).
The same molecular substance in three different states at the same pressure is shown in the diagram above. Based on molecular motion, the temperature of the substance at state Y is __________.
higher than the temperature at state Z
lower than the temperature at state Z
higher than the temperature at state X
the same as the temperature at state X
Which of the following is most likely to happen to a liquid substance when the temperature is increased?
molecular motion of the atoms will decrease, causing it to change from a liquid to a solid
molecular motion of the atoms will decrease, causing it to change to a gaseous state
molecular motion of the atoms will increase, causing it to change to a solid state
molecular motion of the atoms will increase, causing it to change to a gaseous state
Use the diagram to answer the following quetion(s).
The same molecular substance in three different states at the same pressure is shown in the diagram above. Which of the following has MOST likely happened when the substance changes from state Z to state Y?
the melting point increased
the temperature decreased
the temperature increased
the boiling point increased
The effect of temperature change on three different substances is shown in the table. Based on the data, one could conclude that gases change to liquids and liquids change to solids after
decreases in temperature.
increases in temperature.
the three substances react.
chemical changes in temperature.
The diagram shows the same molecular substance in three different states of matter at the same pressure. When the temperature is lowered in the system, the state of the substance can change from _________.
state Z to state Y
state Z to state X
state Y to state X
state X to state Z
Which of the following would BEST complete the concept map?
species extinction rate
energy source usefulness
environmental protection cost
a renewable resource's usefulness
Which option describes an example of converting light energy to electrical energy?
plugging in a desk lamp
switching on a stove burner
turning on a solar–powered calculator
turning on a battery–powered flashlight
A man plugs in an iron to press a shirt. Within a couple of minutes the metal part of the iron is very hot. What type of energy transformation is taking place?
chemical energy to light energy
light energy to electrical energy
thermal energy to chemical energy
electrical energy to thermal energy
Hydroelectric energy uses the natural water movement of rivers, streams, and waterfalls to generate electricity. Which of the following is a negative consequence of the conversion process?
it costs a lot of money to operate
it gives off polluting exhaust
it is driven by nonrenewable resources
it may cause habitat erosion or flooding
Which piece of evidence best supports the idea that energy cannot be created nor destroyed, only changed from one form to another?
A spider can spin a web to trap different insects.
A plant must absorb water through its roots to grow.
A person can grow vegetables to eat in his own backyard.
An animal must eat food to be able to run and move around.
Jill pulls back a ball on a pendulum as shown.
She tells her friend the ball has potential energy. She says that when she lets it go the energy the ball has will be destroyed. Her friend says this is not true. What piece of evidence should Jill's friend mention to support her claim?
When the ball strikes the balls at the bottom, another ball moves. Therefore, the potential energy leaves the ball.
The ball will not move unless it is let go. Therefore, the amount of potential energy in the ball will stay the same until it moves.
The ball moves toward the other balls when it is let go. Therefore, the potential energy it has is not destroyed. It is changed to another form.
As the ball moves downward when it is released, it picks up speed. Therefore, the potential energy it has is not destroyed. More is created before it changes to another form.
If a pot of water is placed over a fire, which of the following transfer of thermal energy would take place?
convection
reflection
transcription
placement
__________ is the energy carried from one object to another because of temperature.
Vibration
Heat
Weather
Water
Heat flow is the transfer of energy from __________.
a cooler object to a warmer object
a solid object to a fluid object
a warmer object to a cooler object
a fluid object to a solid object
What is the law of conservation of energy state?
Energy cannot be created nor destroyed only transformed
Energy is created, destroyed and transformed
Energy can be created and transformed but not destroyed
Energy cannot be created but is transformed and lost
