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

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).
