Final answer:
To convert 19 degrees Celsius to Kelvin, add 273.15 to the Celsius temperature, resulting in 292.15 K.
Step-by-step explanation:
The value of 19 degrees Celsius on the Kelvin scale can be found by using the conversion formula, where Kelvin (K) equals the temperature in Celsius (°C) plus 273.15. Therefore, to convert 19°C to Kelvin:
K = 19°C + 273.15 = 292.15 K
It is important to use the Kelvin scale in scientific work because it is an absolute temperature scale, To convert temperature from Celsius to Kelvin, you need to add 273.15 to the given Celsius value. which means that 0 K is the lowest possible temperature, known as absolute zero, where there is no molecular motion to produce thermal energy.
