Question

Which object is hotter? Multiple Choice -22:49 O Object 1 at T = 0°C Object 3 at T = OK Object 2 at T = 0°F

Answer 1

Answer:

Object 1 is hotter.

Explanation:

Object 1 T=$0^{\circ}C$  

Object 2 T=0 K

Object 3 T=$0^{\circ}F$

Relation between Celcius ,Kelvin and Fahrenheit

$\dfrac{C-0}{100}=\dfrac{K-273}{100}=\dfrac{F-32}{180}$

K=C+273,  $K=\dfrac{5}{9}(F-32)+273$.

So now we will convert all in one unit.

Object 1 T=273 K

Object 2 T=0 K

Object 3 T=255.22 K

From above we can say that Object 2 is coolest and object 1 is hottest.

So  Object 1 is hotter.
