Convert the following temperature to Celsius scale:
a. 0°C =273K
300K= (300 - 273)°C = 27°C
b. 573K= (573 - 273)°C = 300°C
Name A, B, C, D, E and F in the following diagram showing a change in its state.
What produces more severe burns, boiling water or steam?
Why is ice at 273K more effective in cooling than water at the same temperature?
Give two reasons to justify -
(a) Water at room temperature is a liquid.
(b) An iron almirah is a solid at room temperature.
What is the physical state of water at -
