Match the thermal energy transfer methods with the correct definitions for the lava lamp.
Conduction
Heat goes from the light bulb to the gla
Convection
Oil and wax circulates in the bottle
Radiation
Feel the heat coming from the lava
Which observation correctly identifies convection?
The warm wax rises and cool wax sinks in the bottle.
I can feel the heat from bottle when my hands are near it.
The hand gets hot when I touch the bottom of the lamp.
The lamp heats the bottle when it is turned on.
How would having gloves on change how the heat was transferred when touching the lamp?
They slow heat transfer by radiation from the glass bottle to the student’s hands.
They slow heat transfer by convection from the glass bottle to the student’s hands.
They slow heat transfer by conduction from the glass bottle to the student’s hands.
They slow heat transfer by convection from the safety gloves to the student’s hands
