questions: 1. What can you say about the temperature of water before it is boiled, while it is boiling, and after it has boiled? 2. What does the increase in temperature indicate? 3. A 120 J of energy is added to a system that does 40 J of external work, by how much thermal energy of the system is raised? 4. While a gas does 400 J of work on its surroundings, 900 J of heat is added to the gas, What is the change in the internal energy of the gas? 5. The initial energy of the system is initially 35J. The system does 34 J of Work. What is the system's final internal energy when a total of 46 J of energy is added to the system by heat?​
1.Compare the temperature of water before it is boiled while it is boiling and after it has boiled. Answer: ... Water boils at sea level approximately 100°C. When the water boils, hydrogen bond broken and phase changes occur, liquid H₂O will turns to gas H₂O.
2.Increase in temperature means: - The substance is getting hotter. - It's internal energy is rising.
