A bathtub holds 135 L of hot water at 41.0°C. Cold water at 13.0°C is added to the bathtub until the water reaches a final equilibrium temperature of 38.5°C. Assuming only a negligible amount of energy is exchanged between the water and its environment during this time, determine the volume in liters (L) of the added cold water. The specific heat of water is 4.19 ✕ 103 J/(kg · °C) and its density is ρ = 1.00 kg/L. What is the mass of hot water mhot in the bathtub? 135 L 135 kg mhot cannot be determined from the given information. none of the above

An insulated Thermos contains 190 cm3 of hot coffee at 87.0°C. You put in a 13.0 g ice cube at its melting point to cool the coffee. By how many degrees has your coffee cooled once the ice has melted and equilibrium is reached? Treat the coffee as though it were pure water and neglect energy exchanges with the environment. The specific heat of water is 4186 J/kg·K. The latent heat of fusion is 333 kJ/kg. The density of water...
