1. 2. 3. The oxygen we breathe can be condensed into a liquid if its temperature is kept below -297 °F. At -297 °F, liquid oxygen (O₂) is observed to be a boiling liquid. Thus, the boiling point of oxygen is reported as -297 °F. a. What is the boiling point of oxygen in Celsius degrees (C)? b. What is the boiling point of oxygen in Kelvin degrees (K)? c. What is the SI unit for temperature measurements? A 40.00 gram metal sample is placed on a hot plate and the heat energy that flows into the metal is 1.0338 x 10² calories. The metal is observed to rise in temperature from 43.0 to 54.0 °C. Calculate the specific heat (sp.h) of the metal. A 22.0 gram sample of water initially at 58.0 °C is placed in a refrigerator where it loses 880.0 calories of heat. (reminder: for water, sp.h = 1.000 cal/g°C) a. What is the final temperature of the water? b. Is this process endothermic or exothermic? (explain in one sentence)
