Answer:
a) The hot iron is warmer than the shirt.
Step-by-step explanation:
Thermal energy always flows from a hot object to a cold object.
This process is similar to water flowing from a higher level to a lower level.
In the given question, since the iron is hot, it has greater thermal energy compared to the shirt. So heat flow is from the hot iron to the shirt.
( like during the ironing of a shirt).
