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

Ice cubes are used to chill a soda with a mass msoda = 0.300 kg at 15.0 °C. The ice is at 0 °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.
