Water has the following thermodynamic values: δh°fus of h2o = 6.02 kj/mol δh°vap of h2o = 40.7 kj/mol heat capacity of solid h2o = 2.09 j/g°c heat capacity of liquid h2o = 4.18 j/g°c heat capacity of gaseous h2o = 1.97 j/g°c
how much energy (in kj) is required to raise the temperature of 25.0 g of h2o from -129°c to 262°c?
enter your answer in units of kj to three significant figures.
