Heat and Energy Transfer

The diagram represents a beaker of water being heated by a flame. The arrows represent heat transfer occurring in the beaker. (NYS 8th grade Science Test 2019)

Which process is represented by the arrows in the diagram?

• condensation

• conduction

• convection

• radiation

The movement of the liquid in a thermometer shows changes in temperature. An increase in temperature indicates the molecules in the liquid. (NYS 8th grade Science Test 2019)

• moved slower and closer together

• moved faster and spread farther apart

• contracted in size when heated

• expanded in size when heated
