Question 509: Brrrrrr

One of the first to discuss the possibility of an ___________ was __X_____. His 1665New Experiments and Observations_________ articulated the dispute known as the ________. The concept was well known among naturalists of the time. Some contended an___________ occurred within earth (as one of the four so-called 'elements'), others within water, others air, and some more recently within nitre. 


Values of this order for the ____________ were not, however, universally accepted about this period. Laplace and Lavoisier, in their 1780 treatise on heat, arrived at values ranging from 1,500 to 3,000 below the _________, and thought that in any case it must be at least 600 below. Dalton, in his Chemical Philosophy gave ten calculations of this value, and finally adopted a far off, completely wrong value. .


What?
