- Please answer this, I need help.Anice chest at a beach party contains 12 cans of soda at 3.70°C. Each can of soda has a mass of 0.35 kg and a specific heat capacity of 3800 J/(kg C). Someone adds a 8.99-kg watermelon at 25.0°C to the chest. The specific heat capacity of watermelon is nearly the same as that of water. Ignore the specific heat capacity of the chest and determine the final temperature T of the soda and watermelon in degrees Celsius. Number Units Tube Initial FinalSuppose you want to raise the temperature of a 0.185-kg piece of ice from -20.0°C to 130°C. The heat of fusion is Lf = 334 kJ/kg, and the heat of vaporization is Lv = 2256 kJ/kg. In this problem, take 1520 J/kg⋅°C as the specific heat of steam, and 2090 J/kg⋅°C as the specific heat of ice. Part (a) How much heat, in kilocalories, must be transferred for this to happen, including the energy needed for phase changes? Part (b) How much time, in seconds, is required to do this, assuming a constant 20.0 kJ/s rate of heat transfer?
- Arelyz and Hyeonggyun drop a 378.0-g piece of metal at 100.0°C into 447.0 g of water at 20.0°C. The final temperature of the system is measured to be 50.0°C. What is the specific heat of the metal in J/kgK, assuming no heat is exchanged with the surroundings or the cup containing the water? The specific heat of water is 4190 J/(kg K).A 200 g iceball can be launched from a custom launcher at 250 m/s. The iceball is initially at -5oC when it is shot vertically upwards, and by the time the iceball starts to fall down again 10 g of the ice has melted away. What is the maximum height of the iceball? The specific heat of ice is 2100 J/(kg oC) and the latent heat of fusion for ice is 334,000 J/kg.
