First question Aliyah completed four investigations to examine how heat transfers in different situations. Investigation #1

Investigation #2

Investigation #3

Investigation #4

Aliyah placed a bowl of ice cream in the sun, and the ice cream began to melt.

Aliyah placed an ice cube on a heating pad, and the ice cube began to melt.

Aliyah held a piece of chocolate in her hand until it began to melt.

Aliyah placed a piece of cheese on a burger that had just been cooked, and the cheese began to melt.

Which investigation was NOT an example of conduction and why?
A
Investigation #1 is an example of radiation because the thermal energy from the Sun is traveling through space to heat the ice cream and cause it to melt.

B
Investigation #2 is an example of convection because the thermal energy from the heating pad is rising to melt the ice.

C
Investigation #3 is an example of radiation because the thermal energy from her hand is traveling to the chocolate causing it to melt.

D
Investigation #4 is an example of convection because the thermal energy from the burger is rising causing cheese to melt.
