In art class, the students watch a video about creating glass art. Which statement best describes how glass is shaped into a vase?
Glass is melted and is more flexible to shape.
Glass is frozen and is more flexible to shape.
Glass is melted and is less flexible to shape.
Glass is frozen and is less flexible to shape.
Which is most responsible for the uneven heating of the air in the atmosphere?
radiation
convection
conduction
condensation
A metal wire is used in a light bulb to conduct heat until it glows. Which best explains why metal is used?
Metal heats up quickly.
Metal conducts sunlight.
Metal cols down slowly.
People sitting around a campfire are able to feel the heat from the fire. How are the people able to feel the heat from the fire without touching the fire?
The heat from the fire travels through the ground and heats the ground around the people.
The heat from the fire is conducted through air molecules to the people.
The heat from the fire rises in the air and then settles around the people.
The heat from the fire radiates from the fire to the people.
Sue is building a bike with a metal frame in a warm, sunny area. Which material would be best for Sue to use for the grips on the handlebars so that her hands do not get too hot?
Silver metal, because silver reflects heat, and metal conducts heats.
Black metal, because black absorbs heat from the sun, and the metal does not conduct heat.
White rubber, because white reflects heat, and the rubber does not heat up quickly.
Black rubber, because black reflects heat from the sun, and rubber does not conduct heat.
What happens to metal railroad tracks during the heat of a summer day?
decrease in weight
increase in weight
decrease in length
increase in length
Mr. Olivares drinks coffee on his way to work. Today, he poured it into a metal travel mug instead of a paper cup. What will he most likely notice about the temperature of his coffee when he gets to work?
His coffee will be colder, because the is mug is taller.
His coffee will still be hot, because the mug is taller.
His coffee will be colder, because the mug is metallic.
His coffee will still be hot, because the mug is metallic.
On a hot day in the sun, why does Robert use a foam can holder to keep his drink cool?
Foam insulates the cold drink.
Foam reflects cold air from the can.
Foam reflects heat from the sun off the can.
Foam conducts heat between the can and the air.
A family living on the top floor of a tall building complains that their home get too hot during the day. Which could they add to the roof to allow their home to stay cooler?
black metal
white metal
black rubber
white rubber
Bill stands in a swimming pool and notices that the water around his feet is a lot cooler than the water near the surface. Which process causes this difference in temperature?
convection
evaportaion
radiation
conduction
Bob is putting new water pipes in his house. Which material would be best for Bob to use to prevent his pipes from freezing?
aluminum
copper
plastic
steel
Which best explains why the handles of many cooking pans are made of plastic?
Plastic melts easily.
Plastic freezes easily.
Plastic is a poor conductor of heat.
Plastic is a good conductor of heat.
A scientist trying to identify an unknown liquid may heat the liquid. Which would be the BEST reason for scientist to heat the liquid.
to observe a color change
to get rid of most impurities
to identify the boiling point
to collect gases for additional study
How does a greenhouse help a gardener grow plants during a cool season?
The glass transmits light into the greenhouse but is slows the transfer of thermal energy out of the greenhouse.
The glass panels transfer thermal energy into the greenhouse but they do not transfer thermal energy out.
The greenhouse converts light energy into thermal energy so the plants grow faster.
The glass blocks the flow of all types of energy into or out of the greenhouse.
Which is the best example of radiation?
warming hot dogs over a fire
boiling water on a stove-top burner
burning a piece of paper with a candle flame
Which best explains why a refrigerator is usually not made completely out of metal?
Metal will not transfer heat, which allows the refrigerator to remain cool.
Metal easily transfers heat, which would warm the inside of the refrigerator.
Metal would heat up quickly on the outside, making the door too hot to touch.
Metal cools quickly, causing the refrigerator to be too cold and freeze the food inside.
Kayla has a wooden rod, a steel rod, and a glass rod. How could she compare the materials to find out which transfers thermal energy BEST?
Submerge each rod in ice water to find out which loses the most heat.
Place the three rods in a freezer to find out which becomes the coldest.
Place one end of each rod in very hot water to find out which becomes hot the fastest.
Place the rods on a table in a warm room and find out which feels warmest after a period of time.
Which best explains what happens in most materials when they are heated?
They expand.
They contract.
They change color.
They double in size.
Which part of the diagram shows conduction?
Part A
Part B
Part C
Yuko designed an experiment to test the effect of heating and cooling on air. She blew up two balloons to similar sizes and measured their circumferences. She placed one balloon in a freezer for one hour and left the second balloon on the table. After one hour she measured their circumferences again. She then left both balloons on the table for one more hour. The graph below shows the change in the sizes of the balloons during the experiment.
Which statement BEST explains the differences seen between the two balloons during the experiment?
Air contracts when cooled but is not affected by warming.
Cooling causes air to contract and heating causes air to expand.
Balloons put more pressure on cold air than room temperature air.
