In your own words, what is "mass"?
The measure of the amount of particles in an object
The sun shines on the students playing soccer. (p.65)
Conduction, Convection, or Radiation?
Radiation
Is iron a thermal conductor, or a thermal insulator? (p. 83)
Thermal Conductor
Which color T-shirt would heat up MORE on a sunny day?
Black T-shirt, or white T-shirt?
(p. 86)
Black T-shirt
True or false: It is possible to make something colder by adding "coldness" to it. (p. 60)
False
In your own words, what is a thermal conductor?
A material that transfers heat easily / low specific heat
High-temperature particles in one material collide with low-temperature particles in another material and make them move faster. (p.61)
Conduction, Convection, or Radiation?
Conduction
Is wood a thermal conductor, or a thermal insulator? (p. 83)
Thermal insulator
DAILY DOUBLE! For 200 points each, name as many factors as you can that affect how fast heat is transferred between objects. (p.86)
Mass
Specific heat
Exposed surface area
Light angle
Thickness
Reflectivity vs absorbency (color)
Type of material
Size of sample
Environment
Which particles are moving the fastest: solid particles, liquid particles, or gas particles?
In your own words, what is a thermal insulator?
A material that takes a lot of thermal energy to heat up
A thermogram, or heat-vision camera, detects waves of energy emitted from warm objects into space. (p.65)
Conduction, Convection, or Radiation?
Radiation
To protect your skin from heat burns in the kitchen, should you use utensil handles made of thermal conductors, or thermal insulators?
Thermal insulators
Which will heat up faster: A thin material, or a thick material?
Thin material
The more you study for this quiz, the higher your grade goes. Is this DIRECT relationship, or INVERSE relationship? (p.78)
Direct relationship
The total energy of the particles of a substance, as measured by kinetic energy of particles, number of particles, and state of matter.
Thermal Energy
Warm air particles from a toaster rise into the air above the toaster because thermal expansion makes them less dense than the cold air around them. (p.67)
Conduction, Convection, or Radiation?
Convection
To quickly transfer heat from stovetops in the kitchen to the food, should pots and pans be made of thermal conductors, or thermal insulators?
Thermal conductors
Which will heat up a material faster - Sun rays at an indirect angle, or a direct angle?
Direct angle (90 degrees)
Materials with a high specific heat take a lot of energy to heat up. Name three materials have a very high specific heat. (p.82)
Water, ice, water vapor, wood
In your own words, what is "specific heat"?
materials take different amounts of energy to heat up
Ice in the northern Atlantic ocean cools ocean water and it undergoes thermal contraction. It sinks and creates a flow that cycles water and nutrients through the whole ocean system. (p.65)
Conduction, Convection, or Radiation?
Convection
Of all these materials, which is the best thermal conductor? (p. 82)
Wood, Aluminum, Copper, Sand, Iron
Copper
If they have the same mass of liquid, which soup will cool down faster - a tall cup (small surface area) or a shallow bowl (large surface area)? (p.86)
Shallow bowl because it has more surface area
Computers and other electronic devices can easily overheat and even melt. Engineers use the concept of thermal conductors to invent a way to prevent this. What is this invention called? (p. 87)
Heat sink (often paired with a fan)
