PLEASE HELP ME!! Starting with 15.0 g of water at 45.0°C, how much heat is needed to raise it to the boiling point and then completely
convert to water vapor at 100 °C? (Hint: There is both a phase change and a temperature changel)
(Triangle)Hrusion = 6.01 kJ/mol
(Triangle)Hvap = 40.67 kJ/mol
a)3.45 kJ
b)8.45 kJ
c)37.3 kJ
d)5.00 kj
e)33.9 kJ

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

hope it
