Four containers made of different materials, each containing water at 45º C, were set out on a table. The initial temperature of the water was recorded. The temperature of the water was also recorded 15 minutes later.
Container A
Container B
Container C
Container D
Thermal energy always moves from –
large objects to small objects.
dark objects to light objects.
warm objects to cool objects.
smooth objects to rough objects.
Which of the following is an example of heat transfer by conduction?
Sunlight warming a room early in the morning.
A metal spoon getting hot in a bowl of soup.
Warm and cold water circulating in an ocean.
Hot air rising and cold air sinking on a beach.
A student notices that the saucer below a coffee cup becomes warmer after coffee is poured into the cup. Energy was transferred from –
the cup to the saucer by conduction.
the saucer to the cup by conduction.
the cup to the saucer by convection.
the saucer to the cup by convection.
Which of the following is an example of heat transfer through radiation?
A pot of soup warming on a hot burner.
A crayon melting on a hot sidewalk.
Beach sand getting warmed by the Sun.
An egg getting cooked in a pot of boiling water.
While seated next to a camp fire, a person begins to feel the warmth of the fire. Energy is transferred from –
the fire to the person by conduction.
the person to the fire by conduction.
the fire to the person by radiation.
the person to the fire by radiation.
Match the following
The total kinetic eneergy of tiny particles that make up matter; the warmer the matter becomes
Thermal Energy
Measured by a thermometer in degrees (Celsius or Fahrenhiet)
Temperature
The transfer of energy by the movement of electromagnetic waves or subatomic particles
Radiation
Heat transfer caused by the rising of hotter, less dense fluids and the falling of cooler, denser fluids
Convection
Transfer of thermal energy that occurs in solids, liquids, and gases when two substances of different temperatures touch
Conduction
Which of the following sets of tools would be most useful in an experiment measuring the rate of transfer of thermal energy in four different liquids?
Triple-beam balance, beakers, metric ruler
Hot plate, beakers, thermometers
Microscope, funnel, metric ruler
pH meter, test tubes, forceps
In an energy transfer experiment, four blocks of different temperatures are stacked. Where would energy transfer by conduction move downward, from a higher block to a lower block?
Sample 2 to Sample 4
Sample 1 to Sample 2
Sample 3 to Sample 4
Sample 1 to Sample 3
Four containers made of different materials, each containing water at 30º C, were set out on a table. The initial temperature of the water was recorded. The temperature of the water was also recorded 15 minutes later. Which container was the most effective at preventing heat transfer from the water to the environment?
Container P
Container Q
Container R
Container S
When an egg is boiled in a pot of water on the stove, there is more than one kind of heat transfer. Heat is transferred from the stove to the pot directly since they are physically touching. Heat is also transferred from the pot to the egg, carried through the water. What two kinds of heat transfer are represented?
Stove → Pot = radiation, Water → Egg = conduction
Stove → Pot = conduction, Pot → Egg = radiation
Stove → Pot = convection, Pot → Egg = conduction
Stove → Pot = conduction, Water → Egg = convection
A container of hot water was left out on a table. Some of its thermal energy was transferred to the environment. The results in degrees Celsius are shown here. What was the change in temperature resulting from this heat transfer in degrees Celsius? Record and bubble your answer below.
(a)
Which of the following is an example of conduction?
Solar energy warming a room.
Heat rising from the coils of a stove.
Hot air drying a wet towel.
Heat moving from a clothes iron to a shirt.
Four steel blocks were heated to different temperatures and stacked together as shown. In which direction will heat be transferred by conduction?
From Sample 4 to Sample 1
From Sample 2 to Sample 3
From Sample 2 to Sample 4
From Sample 3 to Sample 2
Thermal energy transfer by conduction is accomplished when heat moves from a warmer object to a cooler one by –
moving across a solid barrier.
being carried in a fluid, like air or water.
coming in direct physical contact with it.
traveling through empty space.
Water at 34º C was placed into containers made of four different materials. An initial temperature was taken, and a final temperature was taken after 10 minutes. Which container allowed the most transfer of thermal energy from the water to the environment?
Glass
Wood
Paper
Plastic
