Ответ:
7250=980C(36-25). Convert kj-j immediately so units make sense at the end.
7250=10780C
C= .673 J/g
Ответ:
Based on the graph, the following conclusion is correct
Change of state takes place in portions BC and DE
because the temperature is constant in portion BC (0oC) & DE (100oC) and the only form has been changed from ice to water and from water to vapour respectively.
