Design a temperature scale where the freezing point of water is 0 degrees and its boiling point is 70 degrees. What would be the room temperature on this scale?

- If room temperature is 25.0 Â°C, the temperature on the new scale will be 17.5 Â°.
- If room temperature is 25.0 Â°C, the temperature on the new scale will be 25.0Â°.
- If the room temperature is 25.0 Â°C, the temperature on the new scale will be 35.7Â°.
- If the room temperature is 25.0 Â°C, the temperature on the new scale will be 50.0Â°.

Ice cubes are used to chill a soda with a mass m_{soda} = 0.300 kg at 15.0 Â°C. The ice is at 0 Â°C, and the total mass of the ice cubes is 0.020 kg. Assume that the soda is kept in a foam container so that heat loss can be ignored, and that the soda has the same specific heat as water. Find the final temperature when all ice has melted.

- 19.02 Â°C
- 90.3 Â°C
- 0.11 Â°C
- 9.03 Â°C
