Share:
- 1The larger objects will heat up faster because they absorb more radiation overall.
- 2The larger pizza will heat up faster than the smaller pizza due to its larger surface area.
- 3Both sizes of gulab jamuns will reach the oven temperature in exactly the same amount of time.
- 4The smaller gulab jamun heats up faster than the larger one, and the smaller pizza heats up faster than the larger one.✓
Correct answer
The smaller gulab jamun heats up faster than the larger one, and the smaller pizza heats up faster than the larger one.
