Question

A 0.060 kilogram ice cube at 0.0 degrees celsius is placed in a glass containing 0.250 kilograms of water at 25 degrees celsius. which statement best describes this system when equilibrium is reached? (assume no external exchange of heat)

1. the ice is completely melted and the water temperature is above 0 degrees celsius

2. the ice is completely melted and the water temperature is 0 degrees Celsius

3. part of the ice remains frozen and the water temperature is above 0 degrees celsius

4. part of the ice remains frozen and the water temperature is 0 degrees celsius.

Answer 1

The ice is completely bmelted and the water temperature is above 0 degrees Celsius.

Answer 2

The ice is completely melted and the water temperature is above 0 degrees celsius

Step-by-step explanation:

The initial temperature of ice is 0 degree celsius.

the mass of ice is 0.060 kg

specific heat of ice = 2.108 kJ/kg K

specific heat of water = 4.184 kJ/kg K

mass of water = 0.250 kJ/kg K

initial temperature of water = 25 degree celsius

let final temperature of both ice and water = t degree celsius.

Now to reach this temperature, the ice will melt and the temperature of water will be above 0 degree celsius.
