Everything is yogurt, so specific hea...Temperature:<br />Everything is yogurt, so specific heat is identical.<br /><br />Convert temperatures to Kelvin. Room temperature (65 F) is ~291K, and 113 F is ~318K.<br /><br />We want all 65 tbsp of yogurt to end at 113 F; given that 1/65th of it starts at 291K, what temperature must the other 64/65ths be such that the weighted-average is 318K? Or:<br /><br />(x*64+291*1)/65=318<br /><br />Solving for x, x=318.4<br /><br />In other words, the difference between room temperature and 113 degrees for 1/64th as much mass is within the margin of error of your thermometer.<br /><br />Add the starter at 113, maybe 114.Dale Sheldon-Hesshttps://www.blogger.com/profile/07974707193305445403noreply@blogger.com
