There are three methods by which thermal energy can be transferred into or out of a system. When the particles in contact with each other collide and transfer energy through a medium, this is called (a)   . When energy is transferred because of the movement of matter in a liquid or gas, this is called (b)   . When energy is transferred by electromagnetic waves, this is called (c)   . Of the three methods of energy transfer, the one that does not need a medium (particles of matter) is (d)   .

In the image, the flame causes water in the pot to boil. Consider the pot and the water within as a system. Analyze the image to identify which statements are true about the system?

• Conduction transfers energy from the pot to the water.

• Convection transfers energy through the water.

• Radiation transfers energy from the flame to the pot and water.

• Thermal energy of the water increases as it is warmed.

• Thermal energy of the water decreases as it is warmed.

For a science investigation, students were required to boil water in a beaker. They filled a beaker with water and placed it on a hot plate. After a few minutes, gas bubbles began to form and the water reached a boil. Which type(s) of thermal energy transfer occurred in this investigation?

• Only conduction occurred between the hot plate and the beaker.

• Only convection occurred as heat was transferred by currents in the water.

• Conduction occurred between the hot plate and the beaker, and convection occurred when heat was transferred by currents in the water.

• Convection occurred between the hot plate and the beaker, and conduction occurred when heat was transferred by currents in the water.

Lisa investigates the methods of thermal energy transfer and discovers that multiple forms can occur simultaneously. Move the response to the correct box to identify the primary type of energy transfer that is occurring.
