Convert 420.0 k to °C

420.0 K (Kelvin) to C (celsius) is: 146.85 C

Explanation:

The Kelvin (K) to Celsius (C) formula is K − 273.15 = C.

We need to enter 420 for K in the formula, which gives us:

420 − 273.15 = C.

To solve 420 − 273.15 = C, you will need subtract 273.15 from 420:

420-273.15= 146.85

Therefore, the answer is 146.85.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
