Final answer:
The standard sea level temperature is 15°C. To convert a temperature of 25.0°C to the new scale where water freezes at 0 degrees and boils at 70 degrees, it would be 17.5 degrees on this scale.
Step-by-step explanation:
The standard sea level temperature is 15 degrees Celsius (C). Three temperature scales are commonly used: Fahrenheit (F), Celsius (C), and Kelvin (K). The Celsius scale, in particular, is defined with the freezing point of water at 0°C and the boiling point at 100°C. Therefore, to design a temperature scale where the freezing point of water is 0 degrees and its boiling point is 70 degrees, we can calculate the room temperature on this new scale.
Given that room temperature is usually considered to be 25.0°C, we would use a conversion factor based on the ratio of the new scale to the Celsius scale. Since 100 degrees on the Celsius scale is equivalent to 70 degrees on the new scale, we can calculate room temperature on the new scale using the following method:
(25.0°C / 100°C) ∗ 70 = 17.5
Therefore, the room temperature on the new scale would be 17.5 degrees.
