Question

at what temperature the reading on Kelvin scale is three times that on celcius scale?

guys aseer me fast
I need step by step explanation​

Answer 1

$\huge\boxed{\fcolorbox{red}{yellow}{★ ANSWER : }}$

➡ (K -273)/100 = (C -0)/100

➡ K = 3C

➡ (3C -273)/100 = C/100

➡ 3C -273 = C

➡ 2C = 273

➡ C = 136.5°C

∴ The temperature of the reading on Kelvin scale is three times that on celcius scale at 136.5c or 409.5k.

Answer 2

Answer:

Therefore, at $136.5^{o} C$ or $409.5K$, the temperature is three times higher on the Kelvin scale than it is on the Celsius scale.

Explanation:

Concept:

One Celsius degree and one kelvin are exactly equivalent units on the Kelvin scale. A Kelvin scale rise of one unit corresponds to a Celsius scale increase of one degree. The zero points of the thermometer are the only distinction between these two scales. To convert Celsius  to Kelvin use, $K = ^{o}C + 273.15$.

Given:

Kelvin scale, Celsius scale.

To find:

We have to find that at what temperature the reading on Kelvin scale is three times that on Celsius scale.

Solution:

we know that,

$\frac{( K -273)}{100} =\frac{( C -0)}{100}$

$( K -273)=( C -0)$

As per the question ,

$K = 3C$

Now, put the value of $K$ in it,

$3C -273 = C$

$2C = 273$

$C = 136.5^{o} C$

$136.5^{o}C * 3 =409.5K$

or

$=136.5^{o} C+273 =409.5K$
