ENERGY CONSERVATION Essays - State Functions, Heat Transfer

ENERGY CONSERVATION 1. How does the final temperature compare with the initial temperature of the hot and cold water for trial? The final temperature goes between the temperature of the hot and cold water. If the amount of the cold water is more then the amount of the hot water, then the final temperature will be closer to the temperature of cold water. If the amount of the hot water is more then the amount of the cold water, then the final temperature will be closer to the temperature of the hot water. 2. How does the energy lost by the hot water compare with the energy gained by the cold water? The energy lost by the hot water and the energy gained by the cold water are very close amounts if they both are same mass. If the amount of hot water is more then the mass of the cold water, the energy gained by the cold water will be more then the energy lost by the hot water. If the amount of cold water is more then the mass of the hot water, the energy lost by the hot water will be more then the energy gained by the cold water. 3. What happens to the amount of heat transferred as the amount of water is changed? I know that the amount of water can effect the amount of heat transferred. The amount of heat transferred increases when the amount of water increases. 4. Does your data ( energy difference ) support the law of energy? If not, why? Yes, my data support the law of energy. Conclusion What happens to hot and cold objects when they are brought together? The hot objects will lose energy and the cold object will gain energy from the hot objects. The temperature of the hot objects will go down and the temperature of the cold objects will go up when they are brought together. The final temperature will be between the temperatures of hot and cold objects. ENERGY CONSERVATION Essays - State Functions, Heat Transfer ENERGY CONSERVATION 1.
