Question

Melting point of ice is .

• A. 273 K
• B. 373 K
• C. 0 K
• D. 100 K

Answer 1

The correct option is A 273 K

The process of changing solid to liquid is known as melting.
The temperature at which a solid melts is known as melting point. We know melting point of ice is $0{}^0$C.
The relation between Celcius (${}^0$C) Kelvin (K) scale is as follows;
Kelvin (K) = (${}^0$Celcius) + 273
Therfore, melting point of ice on kelvin scale = 0 + 273
= 273 K.
