Erick lights two fires. Above Fire 1, he puts a long piece of iron and lays a steak on top. Above the Fire 2, he puts a slab of rubber and also lays a steak on top of that.
Which of the following is most likely to happen?
The steak above Fire 1 cooks well because iron insulates the meat.
The steak above Fire 2 cooks well because of conduction.
The steak above Fire 1 cooks well because iron is a good conductor of heat.
The steak above Fire 2 cooks well because there is more radiation.
Breyon is cooking dinner for his family. He puts a pot of water on the stove's hot plate to boil. Which of the following correctly describes the heat transfer occurring on the stove?
The pot is heated by conduction, the water is heated by convection.
The pot is heated by convection, the water is heated by conduction.
The pot is heated by a conductor and the water is heated by an insulator
The pot and water are heated by convection.
When heat is transferred through a fluid (liquid or gas), this type of energy transfer is occurring:
Conduction
Convection
Radiation
Evaporation
Fire warming your hands is an example of what type of heat transfer?
(a)
Heat transferred over a distance, without the use of matter:
Conduction
Convection
Radiation
Evaporation
Touching your hand to the lightbulb causes you to burn your fingers. This is an example of:
Conduction
Convection
Radiation
Evaporation
Conduction is the process of:
increasing temperature
heat being gained because of metal
heat transfer due to direct contact
heat transfer through water
Your father is making a cake in the oven. He puts on mitts and grabs the edges of the pan to pull it out. The mitts are an example of
An insulator
A conductor
A convector
A radiator

The main source of heat on Earth is the sun. How does the sun transfer heat?
Conduction
Convection
Radiation
Evaporation
On a sunny day, some of the air heats up and rises higher into the atmosphere. This is part of the heat transfer known as
Conduction
Convection
Radiation
Evaporation
You leave a metal spoon inside a cup of hot cocoa and go video games for a few minutes. When you come back and grab the spoon, it burns your hand. Why does this happen?
The spoon is a conductor, so the hot cocoa transferred heat through it easily.
The spoon is a insulator, so the hot cocoa transferred heat through it easily.
The hot cocoa is a form of radiation, so it makes metal hot.
The spoon insulated the heat into your hand
