Cambridge Secondary (7-9). Stage 9. MCE Science. Student Book - Unit 10: Transfer of Thermal Energy - Question 37

When you use a smartphone or laptop, thermal energy builds up in the device and can damage the internal components. This is why you might feel the back of your smartphone or the bottom of your laptop becoming warm after it has been in use for some time. The warmth you feel is actually thermal energy being dissipated as unwanted heat.

To prevent this, the device is designed to dissipate heat to the surrounding environment.

Suggest a way in which heat is dissipated from your device.
