lol, you recovered from the Question which i have posted( diamond and graphite) here is another one :P
The density of ice is 1.00 g cm–3.
What is the volume of steam produced when 1.00 cm3 of ice is heated to 323 °C (596 K) at a
pressure of one atmosphere (101 kPa)?
[1 mol of a gas occupies 24.0 dm3 at 25 °C (298 K) and one atmosphere.]
A 0.267 dm3 B 1.33 dm3 C 2.67 dm3 D 48.0 dm
