Imagine your smartphone is like a hot chocolate mug. When you plug it in, it starts to cool down because electricity flows through it. It’s not cold on the outside, it feels colder to your hand because your skin senses the change in temperature as cooling. It's like drinking warm coffee with your hands around a glass of ice water.
Examples
- Your smartphone feels cold when you charge it because your hand senses a temperature change as heat moves from inside to outside.
- It's like putting your hands around a cup that was just taken out of the fridge, even though it’s not super cold, your skin detects the difference.
- A phone charging in the morning may feel colder than one being charged at night.
