2. The diagram below shows the water cycle on Earth. Describe the phase change during step 1. Short answers are OK. Phase change: Evaporation Particle motion Motion: Liquid because there is open space and BEFORE change: there is water Motion: liquid still 2.3 Particle motion and temperature DURING change: Temperature: Increasing because the sun is hitting on it Particle motion AFTER change: Motion: Gas because its in the air and moving freely​

The boiling point of liquids is very high what does it indicate

Asample of air with a volume of 2.20m3 at a pressure of 105 kpa and a temperature of 30c is cooled to 10c and the pressure is reduced to 75.0 kpa. what is the new volume? 6.9 1.34 2.56 43.0 2.88

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.
