The pressure of an ideal gas kept at constant volume is given by the equation p = at where t is the thermodynamic temperature and a is a constant. let a temperature t* be defined by t* = b in ct where b and c are constants. the pressure p is 0.1 atm at the triple point of water. the temperature t* is 0 at the triple point and t* is 100 at the steam point. (a) find the values of a, b, and c. (b) find the value of t* when p 0.15 atm. (c) find the value of p when t* is 50. (d) what is the value of t* at absolute zero? (e) sketch a graph of t* versus the celsius temperature t for -200°c
