A 70.0 g steam sample at 150.0 degree Celsius was converted to ice at -150.0 degree Celsius, calculate the total amount of heat removed in the process.
When the external pressure on a balloon is decreased at constant temperature, what happens to the gas inside. A) The collisions become more elastic. B) the gas undergoes no changes.
You have a volume of 100 L at a concentration of 100 PPM of benzene. If you later sampled from this known concentration at a temperature of 15° C
Benzene has heat of vaporaization 31 kj/mol and at 25 C has vapor pressure of 108 mm Hg the normal boiling point of benzene is ln 760/108 =31/8.314(1/298-1/t2)
A balloon is filled to a volume of 9.00 multiplied by 102 mL at a temperature of 18.0°C. The balloon is then cooled at constant pressure to a temperature of 1.00 multiplied by 102 K. What is the final volume of the balloon?
