The equation of state and the isothermal process
Answers are for parents and teachers.
1
A cylinder holds 20 l of gas at 300 K and 200 kPa. The gas is heated to 600 K and its volume made 10 l. What is the pressure in kPa?
800
2
About what volume does 1 mol of ideal gas occupy at normal conditions (273 K, 101 kPa)?
about 22.4 l
3
5 l of gas expands isothermally from 120 kPa to 30 kPa. What is the final volume (l)?
20
4
Using pV = νRT explain why an isotherm at higher temperature lies farther from the axes.
pV = νRT is larger, so at the same V the pressure is higher.
5
What amount of substance (mol) is 16 g of oxygen (M = 32 g/mol)?
0.5
