What happens if I plug my USB-C iPhone into my 100W USB-C charging cord for my laptop?

Does the phone charge? Does it get hot? Does the brick get hot?

case 1: an cable without chip, conforming to the usb3 spec both devices transfer the highest amount below the cap that is supported case 2 wirth chip: the maximum power transfered is now the minimum between charger, phone and cable.

I already plug my iphone lightning cable to 100W USB-C charging block for my laptop. USB-C doesn't send full power unless the device wants it.
