Question

2.(i). Convert the temperature of 573 K to the Celsius scale.
(ii). Why does steam cause more severe burns than boiling water?
3.(i). Define the following terms: (a). Sublimation (b). Melting point
​

Answer 1

Explanation:

a. 573K to Celsius

573-273= 300°C

b.because steam has more heat in the form of a latest heat,then the boiling water

c. Sublimation- The temperature at which solid convert it to gas at it's atmospheric pressure

Melting point-the temperature at which solid convert it to liquid at it's atmospheric pressure
