Internal Energy
The Purpose of Lesson
- apply the formulas of internal energy of a monatomic and diatomic ideal gas when solving problems
Evaluation Criteria
Students can:
Derive the formula of the internal energy of an ideal gas;
Calculate the internal energy of the gas;
What is the prevailing energy before the ball drops?
What happens to potential energy when a ball falls, and what kind of energy does it transform to?
What happened to the ball when it hit the ground?
Where did the mechanical energy go?
Monatomic gas internal energy
Internal energy of diatomic gas
The internal energy of a triatomic and more than 3 gas atoms
Task
Calculate the internal energy of 1 mole of an ideal monatomic gas at a temperature 127°С.
We explain on which parameters the internal energy of the gas depends;
We derive the formula for the internal energy of an ideal gas;
Calculate the internal energy of the gas.
