Convection Conduction or Radiation
The movement of warm and cool fluids that transfers thermal energy
What are convection currents?
Light is one type of this kind of wave.
What is Electromagnetic Wave
Formation of a gas, formation of a precipitate, or color change
Which of the following are signs of a chemical change?
They form a precipitate of sodium acetate
What happens when you mix vinegar and baking soda?
This phase change occurs when a solid changes directly into a gas without becoming a liquid first.
What is sublimation?
This type of thermal energy transfer occurs when particles collide through direct contact.
What is conduction?
This occurs when a wave passes through matter and carries energy through it?
What is transmission?
The ability of one material to dissolve in another
What is solubility?
By rearranging particles during a chemical reaction
How does a precipitate form?
This type of energy depends on the attraction between particles.
What is potential energy?
The cloth strap of a seat belt is an example of this type of material.
What is a thermal insulator?
A disturbance that transfers energy from one place to another without transferring matter?
What is a wave?
By observing if a new substance forms
How can you determine whether the formation of bubbles is the result of a physical change or a chemical change?
They convert only about 20-30% of the chemical energy in fuel into mechanical energy, with the rest lost as heat.
Why are heat engines, such as those in most automobiles, not highly efficient?
This phase change occurs when a solid becomes a liquid.
What is melting
Warm air inside a hot-air balloon becomes less dense and rises because of this type of thermal energy transfer.
What is convection?
This electromagnetic wave is commonly used to create images of bones?
What is an x-ray
By observing if a new substance forms
How can you determine whether the formation of bubbles is the result of a physical change or a chemical change?
temperature
Which is held constant when a gas obey's Boyle's law?
When dry ice changes directly from a solid to a gas, what phase change is occurring?
What is sublimation?
Convection happens during this process.
What is when warm air rises and cool air sinks?
The bending of light called when it changes speed in a new material?
What is refraction?
The burning of trees produces ash and gases, which are new substances and may contain harmful toxins.
Which of the following describes a physical change during a wildfire?
The relationship between a gas's pressure and volume when temperature stays constant
What does Boyle's Law describe?
During a wildfire, the water inside trees undergoes this physical change as it is heated.
What is evaporation?
