Question

Repeat the preceding problem with 2.00 kg of ice instead of 1.00 kg.

a) Final temperature: -1.2°C, Ice melted: 0.45 kg
b) Final temperature: -1.5°C, Ice melted: 0.60 kg
c) Final temperature: -1.8°C, Ice melted: 0.75 kg
d) Final temperature: -1.0°C, Ice melted: 0.30 kg

Answer 1

To find the final temperature when pouring 0.0100 kg of 20.0°C water onto a 1.20-kg block of ice initially at -15.0°C, you can use the concept of heat transfer. Solve the given equation to determine the final temperature and the mass of ice melted for each option.

Step-by-step explanation:

To find the final temperature when pouring 0.0100 kg of 20.0°C water onto a 1.20-kg block of ice initially at -15.0°C, we can use the concept of heat transfer. The heat transferred to the ice and water is given by the equation:

**m_ice * L_f + m_ice * c_w * (T_f - 0°C) = -m_water * c_w * (T_f - 20.0°C)**

Using the given values from each option, we can solve for the final temperature (T_f) in each case. The correct option is the one that satisfies the equation. The final temperature and the mass of ice melted can be determined for each option.
