Question

A $1K$ rise in temperature is
A. Same as a $1^\circ C$ rise in temperature
B. Same as a $1^\circ F$ rise in temperature
C. More than a $1^\circ C$ rise in temperature
D. Less than a $1^\circ F$ rise in temperature

Answer 1

$1^\circ C$ is read as one Celsius and $1^\circ F$ is read as one Fahrenheit. Now we want to know what’s the difference between the two. $1^\circ F$ is used in the United States and $1^\circ C$ in all other countries.

Formula used:
Formula for converting is $^\circ F = \left( {\dfrac{9}{5} \times ^\circ C} \right) + 32$

Complete step by step answer:
Firstly, what is the rise in temperature? The basic answer is to heat which can be done by increasing the load or by giving high energy to the system. We can find the rise in temperature simply by subtracting the initial temperature with the final temperature.Firstly, revising the formula to convert kelvin into Celsius or Fahrenheit
$^\circ C = K - 273$
$K = \dfrac{5}{9}\left( {^\circ F - 32} \right) + 273$
Which means if you have temperature expressed in Celsius, then just need to add $273.15$ to convert it into absolute temperature that is one kelvin.

And we want to convert the temperature expressed in Fahrenheit, then subtract it from $32$ then multiply with $\dfrac{5}{9}$ followed by adding $273$ to convert it into absolute temperature in one kelvin. $1K$ rise in temperature is exactly equal to the $1^\circ C$ rise in temperature. T

hese two quantities have the same size; the only difference between the two is where the two scales have their zeros. Absolute zero temperature is $0K$ and $0^\circ C$ is the freezing point of water. While the boiling point of water is $100^\circ C$ which is equal to the $373.15K$.

Hence the correct option is A.

Note: The relation between the degree Celsius and the degree Fahrenheit are proportional to each other. Children got confused that either the Fahrenheit will come on the left-hand side or on the right-hand side. So, learn the relationship carefully.
