Question

convwrt 20 degree celcius in to kelvin scale

Answer 1

1 degree celcius = 273 degrees kelvin
So,
20 degrees celcius = 20+273
                            = 293K
therefore, 20 degrees celcius = 293 degrees kelvin

Answer 2

Temperature on Kelvin scale = 273 + Temperature of Celsius scale
                                           = 273 + 20°
                                           = 293 K
