option 2 is correct
coffee is always in liquid form, therefore it's bond energy will not change, only thermal energy will change.
water was in solid form and converted to liquid form, therefore it's bond energy will change also it is getting heated, so thermal energy will also change.
You make a cup of hot coffee and pour it into an insulated container that already...
A hot block of iron is placed on top of a block of ice at Tiwater--60° C in an insulating container so no heat can be transferred into or out of the container. When you open the container later the ice has completely melted. For the physical system of the iron and water, what energy systems changed from the time the iron is placed insided to the time the container is opened? Ebond, water O Ethermal, iron, Ethermal, water Ethermal...
On a winters day in Boston I left a cup of coffee in my car, where it froze. When I remembered my coffee, I brought it inside and used a microwave to heat it back up to 80°C so I could drink it. Consider an energy-interaction model for the physical system consisting of the cup and the coffee. What energy systems are changing from the time the microwave is turned on to the time it stops? Ebond, coffee Ebond, coffee,...
Question 3 1 pts You put a cup of hot tea on the counter and forget to drink it. When you come back three hours later the contents of the cup are at room temperature. For the physical system of just the tea, what energy systems changed from when you put down the cup to when you came back three hours later? Ethermal, tea Ebond, tea O Ethermal, tea. Ebond, tea, Ethermal, cup Ethermal, tea. Ebond, tea, Ethermal, cup. Ebond,...
Fill the graduated cylinder with hot tap water and let stand for one minute. Pour water into the sink. Measure 70 mL of hot water. Pour the water into the foam cup. Measure the temperature of the water. Add an ice cube to the cup of water. Gently swirl the cup. Measure the temperature of the water as soon as the ice cube has completely melted. Pour the water into the graduated cylinder and measure the volume. The initial temperature...

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...
An insulated Thermos contains 200 cm3 of hot coffee at 80.0°C. You put in a 16.0 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...
A hot block of iron is placed on top of a block of ice at Ti water = -60° C in an insulating container so no heat can be transferred into or out of the container. When you open the container later the ice has completely melted. For the physical system of the iron and water, what energy systems changed from the time the iron is placed insided to the time the container is opened
Your 200g cup of coffee is boiling hot (100 degrees celcius). You throw in 50g of -15 degrees celcius of ice to cool it off. Assuming negligible heat leaves the coffee-ice system during this process, what is the final temperature of your coffee? (The specific heat capacity of ice is 2.03 J/(g degree C and the specific heat capacity of water is 4.18 and the latent heat of melting for ice to water is 334J/g).
Chapter 18, Problem 035 An insulated Thermos contains 150 cm3 of hot coffee at 86.0°c. You put in a 18.0 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...
