A teacher puts one test tube of 50 degree C liquid and one test tube of 10 degree C liquid into a 20 degree C water bath, as shown in the diagram below. Which of the following diagrams best represents the directions that heat will move when the test tubes are placed into the water bath?
The more particles a substance has at a given temperature,
The higher its temperature
The more thermal energy it has
The more degrees it has
The more kelvin it has
The movement of thermal energy from a warmer object to a cooler object is called
Heat
Temperature
Motion
Momentum
Heat transfer occurs
In many directions
Both from warm objects to colder ones and from cold objects to warmer ones
Only from warm objects to colder ones
Only from cold objects to warmer ones
The transfer of energy by electromagnetic waves is called
Conduction
Convection
Radiation
Insulation
Which of these is a good conductor?
Wood
Paper
Silver
Air
A measure of the average kinetic energy of the individual particles in an object is called

Which of the following is an example of conduction?
Warm and cold water circulating in an ocean
Sunlight brightening a room early in the morning
A ceramic mug becomes warmer after coffee is poured into it
Hot air rising and cold air sinking on a coast line
Currents developed as heat is transferred in liquids through the process of –
Conduction

Radiation
While seated one meter away, a camper felt the warmth of the camp fire. Which type of energy transfer did the camper experience?
Conduction
Convection
Radiation
All of the following are examples of heat transfer by radiation EXCEPT –
Solar energy warming the earth
Heat from the red hot coils of a stove
A light bulb warming the surrounding air
Heat moving from a clothes iron to the fabric as a shirt is ironed
Why does ice melt when placed in a room temperature container?
Heat is transferred from the ice into the container.
Heat moves from air and the container into the ice.
The ice loses the energy needed to hold it together as a solid.
Atoms of the water molecule come apart.
In an energy transfer experiment, four rocks of different temperatures were placed against the side of a large block of ice. On which side of the block of ice would the most melting occur?
North
South
East
West
In an energy experiment, a student places 500 mL of water in a beaker along with several noodles. After heating the water, she noticed the noodles circulating in the beaker. Which of the following was her experiment designed to test?
Conduction
Convection
Radiation
A chef leaves a copper spoon, a wooden spoon, and a steel spoon in a pot of boiling soup for several minutes. Which spoon should the chef grab with his bare hand to stir the soup?
The copper spoon
The steel spoon
The wooden spoon
The three spoons will be equally hot
Why does warm air rise?
It is more dense
It wants to contract
It is less dense
Warm air does not rise.
Convection can take place in _________________.
solids only
liquids only
liquids and gases only
solids, liquids and gases
