Question

s. Consider propane, which has a normal boiling point of -42.0°C and a heat of vaporization of 19 kJ/mol. What is the vapor pressure at 25.0°C? 6. Atmospheric pressure on the surface of Mars averages 600 Pa (6 mbar) Use the phase diagram for water below to determine the boiling and melting points for water on the surface of Mars, assuming an atmospheric pressure of 800 Pa. Note that this chart uses a logarithmic scale, so the axes major unit divisions look a little strange. a. i. The melting point is ii. The boiling point is Assuming a pressure of 800 Pa, identify the phase water will likely be in at the following temperatures (circle your answer). b. L At -100 °C (low Martian temperature), water will be solid / liquid/gas ii. At-53.15 °C (average Martian temperature), water will be solid / liquid / gas i At 16.9 °C (high Martian temperature), water will be solid / liquid /gas 1.155 ?. 2009 MPS Critical point b 647 K. 22.064MP' 100??

Answer 1

a. 1) The melting point of water is 0 degree celcius or 273.16 K

2) The boiling point is 100 degree celcius or 373.15 K

b. 1) it is in solid state

2) It is in vapour state

3) It is in vapour state
