Final Equil. of 0.03 kg Ice & 0.18 kg Water @ 25°C

In summary, when 0.03 kg of ice and 0.18 kg of water reach equilibrium at 25°C, the final temperature is 0°C due to the equalization of temperatures between the two substances. The amount of heat required to melt the ice and raise the temperature of the water to 25°C is approximately 666.6 Joules. The final equilibrium temperature will be the same regardless of the initial temperatures of the ice and water, as the substances will reach thermal equilibrium. The mass of the ice and water does not affect the final equilibrium temperature, which is solely determined by the specific heat capacity and latent heat of fusion of the substances. The physical process that occurs during the final equilibrium is melting, as heat is

0.03 kg of ice and 0.18kg of water are initially in equilibrium at 0 degree celcius in a container. Steam at 100 degree celcius is then passed by in until all the ice melted. The final temperature of the mixture as measured is 25 degree celcius. How much water is in the container in the final equilibrium ? Assume no heat loss or heat gain through other means.

1. What is the final temperature when 0.03 kg of ice and 0.18 kg of water reach equilibrium at 25°C?

The final temperature when 0.03 kg of ice and 0.18 kg of water reach equilibrium at 25°C is 0°C. This is because at equilibrium, the ice and water will have the same temperature, and 0°C is the melting point of ice.

2. How much heat is required to melt the 0.03 kg of ice and raise the temperature of the resulting water to 25°C?

The amount of heat required to melt 0.03 kg of ice and raise the temperature of the resulting water to 25°C is approximately 666.6 Joules. This can be calculated using the specific heat capacity of water and the latent heat of fusion of ice.

3. Will the final equilibrium temperature be different if the initial temperatures of the ice and water are different?

No, the final equilibrium temperature will be the same regardless of the initial temperatures of the ice and water. This is because at equilibrium, the temperatures of the ice and water will equalize to reach a state of thermal equilibrium.

4. How does the mass of the ice and water affect the final equilibrium temperature?

The mass of the ice and water does not affect the final equilibrium temperature. The final equilibrium temperature is solely dependent on the specific heat capacity and latent heat of fusion of the substances involved.

5. What is the physical process that occurs during the final equilibrium of ice and water?

The physical process that occurs during the final equilibrium of ice and water is melting. As heat is transferred from the surroundings to the ice, the ice melts and the resulting water increases in temperature until it reaches thermal equilibrium with the ice.
