Question

On converting 400 K, 380 K and 350 K to Celsius scale, the correct sequence of temperatures will be
a.127 °C, 107 °C and 77 °C
b.126 °C, 105 °C and 75 °C
c.107 °C, 127 °C and 77 °C
d.77 °C, 107 °C and 107 °C​

Answer 1

Lets convert :-

$\boxed{\sf 1°C=273K}$

Solution:-1:-

$\\ \sf\longmapsto 400K=400-273$

$\\ \sf\longmapsto 400K=127°C$

Solution:-2

$\\ \sf\longmapsto 380K$

$\\ \sf\longmapsto 380-273$

$\\ \sf\longmapsto 107°C$

Solution:-3

$\\ \sf\longmapsto 350K$

$\\ \sf\longmapsto 350-273$

$\\ \sf\longmapsto 77°C$

Option A is correct
