What kind of energy transfer is a lamp?
The battery is a store of internal energy (shown as chemical energy). The energy is transferred through the wires to the lamp, which then transfers the energy to the surroundings as light. These are the useful energy transfers – we use electric lamps to light up our rooms.
Is a lava lamp convection or radiation?
The movement of wax in a lava lamp is similar to convection currents that occur in the earth’s mantle, and in the air. A heat source can heat up air or liquid, causing it to become less dense and rise.
What type of change is a lava lamp?
It sinks straight through the oil without any chemical reactions occurring. When it touches the water, however, a chemical reaction occurs that releases carbon dioxide gas bubbles.
Where is conduction in a lava lamp?
Conduction is the transfer of heat through direct contact (in this case, metal coil contact with the “lava” at the bottom of the lava lamp).
Is a lava lamp a physical or chemical change?
We made a lava lamp. It was a chemical change because you can’t change it back to oil, water and barocka’s!!!
