Two vessels contain water and ice at a temperature of 0 degrees. Which of the substances has the greatest internal energy if their masses are the same?
When ice is heated, its temperature does not rise until it melts. The supplied heat is spent on the destruction of the crystal lattice. Therefore, the internal energy of water at 0 ° C is greater than the internal energy of ice at the same temperature. The amount of heat required to melt 1 kg of ice is called the specific heat of fusion. The specific heat of melting of ice is 340,000 J / kg and is numerically equal to the specific heat of crystallization.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
