1. If equal masses of aluminum and copper are heated with same amount of heat, which would reach the higher temperature? Explain your answer.
14. Answer this question: suppose equal masses of hot copper and hot aluminum are added to equal amounts of water. The initial temperatures of the metals are the same and the water samples also start with the same temperature. If the systems are isolated, which system, the one with copper or the one with aluminum, will end up with the higher equilibrium temperature and why?
Which material would cause a more severe burn if equal masses of two distinct metals are heated to a temperature of 100 °C: the one with the higher specific heat capacity or the one with the lower specific heat capacity? Explain your answer using the definition of specific heat.
A 750 g block of copper is heated to 250 degrees C. It is placed in a 350 g aluminum vessel that contains 200 g of water at 5.00 degrees C. What is the final temperature of the copper, water, and aluminum vessel? Specific heat of copper = 0.093 cal/g C degrees Specific heat of aluminum = 0.215 cal/g C degrees Specific heat for water = 1.0 cal/g C degrees
A 22.0g block of aluminum is heated to 190 o C. It is then placed in a calorimeter containing 230.ml of water at 15.6 o C. The density of water is 1.00g/ml. What is the final temperature?
If a copper and aluminum (with different heat capacity) were both heated to 200C and then dropped into a separate but same water bath(35C), after the temperature stabilizes, what would the temperature in the water baths be like? Would they both have the same temperature or would one of the water baths be warmer than the other? and why?
12. A 505-g piece of copper tubing is heated to 99.9 °C and placed in an ins containing 59.8 g of water at 24.8 °C. Assuming no loss of water and a heat capacity for the vessel of 10.0 J/K, what is the final temperature of the system (c of copper = 0.387 J/g.K)? q copper = q water .کرد )
A 65.00 gram piece of Aluminum is heated to 80.0 0c. It is then placed in 135.00 mL of 26.00 0 water. The final temperature of the water with the metal in it is 31.0 0 heat of the aluminum? C. What is the specific
A 130.0 g piece of copper (specific heat 0.38 J/g・°C) is heated and then placed into 400.0 g of water initially at 20.7°C. The water increases in temperature to 22.2°C. What is the initial temperature of the copper? (The specific heat of water is 4.18 J/g・°C and the density of water is 1.00 g/mL).
A 25 gram sphere of aluminum is heated to 95.5°C and placed in a well-insulated container containing 100.0 mL water at 25.5°C. What is the temperature of the water after thermal equilibrium is reached?
