This is anything that has mass and takes up space.
What is matter
In this state of matter, particles are tightly packed and vibrate in place
What is a solid
This type of heat transfer occurs when thermal energy moves through direct contact between particles.
What is conduction
An ice cube melts on the kitchen counter. What type of change is occurring?
What is a physical change
This is the smallest unit of an element that still has the properties of that element.
What is an atom
This property tells you how much space an object takes up.
What is Volume
As the temperature of a substance increases, what happens to the kinetic energy of its particles?
What is it increases
You feel heat from a campfire even though you are not touching it and there is air between you and the fire. This type of heat transfer is primarily responsible.
What is radiation
A silver bicycle is left outside in the rain and eventually develops a green coating. What type of change occurred?
What is a chemical change
This scientist's famous equation, E = mc², showed that mass and energy are related.
what is Albert Einsteine
An object has a mass of 42g and a volume 6 centimeters cubed what is the density
7 grams/centimeters cubed
When thermal energy is removed from a substance, how does the motion of its particles change?
What is the particles move more slowly
This type of heat transfer occurs when warm, less-dense fluid rises and cool, denser fluid sinks, creating a circulation pattern.
What is convection
Water vapor comes into contact with a cold window and changes into tiny drops of liquid water. What phase change is occurring?
What is condensation
This is the only common substance that naturally exists on Earth as a solid, liquid, and gas.
What is water
Two objects have the same volume, but Object A has a mass of 20 g and Object B has a mass of 50 g. Which object has the greater density?
What is Object B
A liquid is heated but does not yet boil. Explain what is happening to the particles and their kinetic energy.
What is the particles moving faster because they are gaining kinetic energy
A student holds a metal spoon in a cup of hot water. After several minutes, the handle becomes warm even though it never touches the water. Identify the primary method of heat transfer through the spoon.
What is conduction
Liquid water is heated until it changes into water vapor. The particles gain enough energy to move much farther apart and escape the liquid. What phase change is occurring?
What is vaporization
This state of matter makes up most of the Sun.
What is plasma
An object has a mass of 72 g and a density of 8 g/cm³. The volume of the object is what?
What is 9 cm³
A gas is cooled until it becomes a liquid. Describe what happens to the particles' energy, motion, and spacing.
What is the particles lose kinetic energy, move more slowly, and move closer together
A pot of water is heated on a stove. Explain how all three methods of heat transfer—conduction, convection, and radiation—can be involved in heating the water.
What is conduction transferring energy from the burner to the pot and through the pot, convection circulating the heated water, and radiation transferring thermal energy from the burner/flame to surrounding objects?
On a cold winter morning, a layer of frost slowly disappears from a frozen car windshield without first becoming liquid water. What phase change is occurring?
What is sublimation
This strange substance can behave like both a solid and a liquid when you push or hit
