A piece of metal at 100 ℃ has its Celsius temperature doubled. By what factor does its kelvin temperature increase?

Answer 1

To convert from °C to K, add 273.15. So a piece of metal at 100 °C is at 373.15 K. A piece of metal at 200 °C is at 473.15 K which is a ratio (or factor) of 473.15/373.15 = 1.27
