Calculate the energy required to heat 1.70kg of ammonia from 39.3C to 507C. Assume the specific heat capacity of ammonia under these conditions is 4.70J*g-1*K-1. Round your answer to 3 significant digits.
Name (please print): Heat Capacity of an Unknown Metal Post Lab Questions 1.) When determining the heat capacity of the unknown metal we assumed the heat capacity of the water has a value of 4.186J/g®C. Is there an error(s) in making this error? Explain The possibility of error in the experiment can be loss of heat, the thermometer not being precise enough to give accurate values, and the capacity of the thermometer is being ignored 2.)
