A temperature scale is defined by the equation ts/ti = lim pi-0 (ps/pi)=1.36609 as in gas thermomery , but now the reaumur scale is adopted by using the additional relation ts-ti = 80. note subscripts 's' and 'i' refer to steam and ice points) a) determine absolute numerical value of the steam and ice points on this scale b) the melting point of tungsten is 6191 f while the -452. If what do these values correspond to on the reaumur scale.
