Thank you for the opportunity to help you with your question!

Initial temp in kelvin scale is 21+273.15=294.15 K

The final temp in kelvin scale is 29+273.15= 302.15 K

Change in temperature = 8 K

Percentage change = (8/294.15)*100= 2.7%

Please let me know if you need any clarification. I'm always happy to answer your questions.
