Argon has normal boiling and freezing points of 87.3 K and 83.8 K, respectively. The triple point of argon occurs at 83.8 K at 0.68 atm. What physical change can be observed - if any - when the temperature of an argon sample is increased from 85 K to 90 K at a constant pressure of 0.46 atm? no physical change occurs - the sample is gas and stays gas solid to liquid liquid to gas no physical change occurs - the sample is liquid and stays liquid solid to gas
