Joseph Black developed the analytical balance
The analytical balance based on a light-weight beam balanced on a wedge-shaped fulcrum. Each arm carried a pan on which the sample or standard weights was placed. It far exceeded the accuracy of any other balance of the time and became an important scientific instrument in most chemistry laboratories -
Joseph Black studied the propties of carbon dioxide

Joseph Black discovered Latent Heat
Referred to the heat transferred that caused a change of volume while the thermodynamic system was held at constant temperature -
Sir Benjamin Thompson, Count Rumford - heat could be manufactured
Heat could be manufactured by the motion of workers. He was the first to realize that heat and mechanical energy were related. BIO: March 26, 1753 – August 21, 1814
