Answer to Question #95225 in General Chemistry for Erica

Question

If you strated with 50 grams of water at 90C and raised the temperature to 110C. Explain how this would support the Law of Conservation or Mass and Energy

Answer 1

At a temperature of 100 degrees Celsius, the water will begin to boil, i.e., form water vapor - go into a gaseous state of aggregation.

Moreover, based on the Law of conservation of mass, if at a temperature of 90 degrees Celsius the mass of water was 50 grams, then at 110 degrees Celsius the mass of water vapor will also be 50 grams.

Based on the Energy Conservation Law, the energy that was given to water and followed by its heating was spent on heating water from 90 to 100 degrees Celsius, then on the process of steam formation, and after that on heating water vapor from 100 to 110 degrees Celsius.

IMPORTANT! As in any real system, in practice, energy was also expended in thermal dissipation.
