> ⇒136.5×3=409.5 ⇒136.5oC+273=409.5K ∴ The temperature of the reading on the Kelvin scale is three times that on the Celcius scale at 136.5 0C or 409.5K. 6 Answer VerifiedHint: The relation between the Fahrenheit and centigrade is linear in nature. We will use the relation between the two scales and place the value of temperature given in the question Formula used: In this solution, we will use the following formula: $ C = \dfrac{5}{9}(F - 32) $ where $ C $ is the temperature in the centigrade scale and $ F $ is the temperature in Fahrenheit scale.Complete step by step answer Additional information In the Fahrenheit scale, the reference temperatures are $ 32\;^\circ F $ as a freezing point of water and $ 212\;^\circ F $ as a boiling point of water. Whereas in the Celsius scale $ 0\;^\circ C $ is the freezing point of water and $ 100\;^\circ C $ is the boiling point of water. Both scales are related directly and linearly which means that if the temperature of an object rises, its value rises both in the centigrade and in the Fahrenheit scale. The common point of both scales is $ - 40^\circ C $ which means that both the centigrade and the Fahrenheit scales will have the same value i.e. $ - 40^\circ C = - 40^\circ F $ .Note We must know the conversion of different temperature scales to answer such questions. Celsius and Fahrenheit are the most widely used temperature scales worldwide along with the Kelvin scale so we must at least know their interconversions. |
