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

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change? work power gravitational energy chemical energy

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c. m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
