- A 266-g block of gold at 76.0°C is immersed in 155 g of water at 25.0°C. Find the equilibrium temperature, assuming the system is isolated and the heat capacity of the cup can be neglected.°CA person pours 0.300 kg of hot water—initially in a pot at 70.0°C—into a 0.120 kg steel cup initially at 20.0°C. What is the equilibrium temperature?The value of specific heat for copper is 390 J/kg⋅∘C, for aluminum is 900 J/kg⋅∘C, and for water is 4186 J/kg⋅∘C. What will be the equilibrium temperature when a 265 g block of copper at 255 ∘C is placed in a 155 g aluminum calorimeter cup containing 815 g of water at 15.0 ∘C?

What is the final temperature of the water, in degrees Celsius?Lead pellets, each of mass 1.60 g, are heated to 200°C. How many pellets must be added to 451 g of water that is initially at 20.0°C to make the equilibrium temperature 25.0°C? Neglect any energy transfer to or from the container.I combine ice with water. The ice has a mass of 10 kg and a temperature of -14°C. The water has a mass of 3.5 kg and a temperature of 14°C. What is the state of the system once it has equilbrated? The system will be all water with a temperature between 0 and 14°C. The system will be solid ice with a temperature between -14°C and 0°C. The system will be a mixture of ice and water at a temperature of 0°C. There will be more ice and less water than the system originally contained. O The system will be a mixture of ice and water at a temperature of 0°C. There will be more water and less ice than the system originally contained.

- A(n) 80-g ice cube at 0°C is placed in 990 g of water at 22°C. What is the final temperature of the mixture? °CA balloon filled with 3.50 kg of water at a temperature of 22°C is dropped from rest from an airplane. The airplane is 8000 m above the ground. There is air resistance acting on the balloon, and just before hitting the ground, the balloon is traveling at a speed of 200 m/s. For this problem, you can ignore the balloon material (its mass, specific heat etc…) and just treat the balloon as 3.50 kg of pure water. Also, assume g is a constant 9.8 m/s^2 during the entire fall and that the system of the water + surrounding air is a closed system. Assume that all internal energy change occurs in the water. a) Find the temperature of the water in the balloon just before hitting the ground. ( cm, water = 4186 J/kgK)
