If 10 grams of ice at 0 degrees Celsius is added to 40 grams of water at 15 degrees Celsius, what is the temperature of the mixture?

A. 5 degrees Celsius
B. 10 degrees Celsius
C. 15 degrees Celsius
D. 20 degrees Celsius

Answer :

Final answer:

The problem is about determining the final temperature after 10 grams of ice at 0°C is added to 40 grams of water at 15°C, which is a physics problem related to thermodynamics and the transfer of heat.

Explanation:

The question involves a thermodynamics calculation which falls under the subject of Physics. Specifically, it's a problem that deals with the transfer of heat between ice and water until thermal equilibrium is reached. The calculation requires knowledge of specific heat capacities, the mass of the substances involved, and the latent heat of fusion for ice.

Calculations based on the given information - adding 10 grams of ice at 0°C to 40 grams of water at 15°C - involve using the formula Q = mcΔT for heat transfer and considering the heat absorbed by the melting of ice. Therefore, the temperature of the mixture will depend on the amounts of heat lost by the water and gained by the ice until the ice melts completely and the system reaches equilibrium.
