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

Object 1 is hotter.

Step-by-step explanation:

Object 1 T=
`0^(\circ)C`

Object 2 T=0 K

Object 3 T=
`0^(\circ)F`

Relation between Celcius ,Kelvin and Fahrenheit

`(C-0)/(100)=(K-273)/(100)=(F-32)/(180)`

K=C+273,
`K=(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.
