Volume of 1KG of benzene phase changing to gas
Thread Content
I need to know the volume occupied by 1 KG of benzene when it transitions from a liquid to a gas. Urgent! This post was last edited by *aohe8888 on 2009-3-15 20:10]
What state is your gaseous form in? At standard conditions: 1000/78X22.4 L; to convert, use the gas law
Well, I agree with what was said above; it depends on the condition. . .
When asking a question, it’s important to clarify the conditions first; the temperature and pressure of gaseous benzene directly affect its volume. The second floor already gives you the volume of it in its standard state; you still need to convert it to the volume in its operating state.
It can be expressed directly in terms of cubes, which also makes calculations easier. 1*22.4/78=0.287 cubic
It can be calculated using the ideal gas law, but the conditions provided by the original poster are incomplete; temperature and pressure are not given.
OP, temperature and pressure of benzene vapor are required to make the calculation. For values less than 0.2 MPa, calculation is done as for an ideal gas; for values greater than 0.2 MPa, corrections are required.
It’s difficult to make calculations without considering temperature and pressure; treating benzene as an ideal gas results in significant errors. It’s okay for rough estimates, but not for precise calculations, as corrections are necessary. The relevant formulas can be found in chemical thermodynamics; there are correction formulas available there
I’m sorry I didn’t explain clearly. Temperature 83 ； The pressure is around 0.2 MPA.
