Imagine that an international commission has defined a new temperature scale, where the absolute zero is defined as 0◦ N and the freezing point of water as 100◦ N. What is the value of the boiling point of water on this new scale? What would be the value of the Boltzmann constant k in J/◦ N?
Which of the following is not true? a. The freezing point of sea water is lower than the freezing point of pure water. b. The boiling point of a water sample from the Salt Lake is lower than the boiling point of pure water. c. The freezing point of 0.1 M NaCl is lower than the freezing point of 0.05 M NaCl.
In a student experiment, a constant-volume gas thermometer is calibrated in liquid nitrogen (−196°C) and in boiling pentane (36.1°C). The separate pressures are 0.344 atm and 1.423 atm. Hint: Use the linear relationship P = A + BT, where A and B are constants. (a) What value of absolute zero does the calibration yield? °C (b) What pressure would be found at the freezing point of water? atm (c) What pressure would be found at the boiling point of water?...
7. You are calibrating a thermometer to use for several experiments. The freezing point reads -3.00C and the boiling point is 102.0C. Show the calibrations calculations. 8. You are using the same thermometer you just calibrated in #7 for melting point that reads 125.0C. What is the actual melting point of the chemical? 9. You are using the same thermometer from #7 for a distillation experiment. According to the lab, you should be collecting distillate in the specific range of...
