Answer :
(a) -77.0 °C on the Fahrenheit scale is approximately -106.6 °F.
(b) 125 °F on the Celsius scale is approximately 51.7 °C.
In order to convert temperatures between Celsius and Fahrenheit scales, we use specific conversion formulas. Let's start with part (a) where we need to convert -77.0 °C to Fahrenheit.
To convert Celsius to Fahrenheit, we use the formula: F = (C × 9/5) + 32
where F is the temperature in Fahrenheit, and C is the temperature in Celsius.
Substituting the given value, we have:
F = (-77.0 × 9/5) + 32
F = (-138.6) + 32
F = -106.6 °F
Now, let's move on to part (b) where we have to convert 125 °F to Celsius.
To convert Fahrenheit to Celsius, we use the formula: C = (F - 32) × 5/9
where C is the temperature in Celsius, and F is the temperature in Fahrenheit.
Substituting the given value, we get:
C = (125 - 32) × 5/9
C = 93 × 5/9
C = 51.7 °C
In part (a), we converted -77.0 °C to Fahrenheit using the conversion formula F = (C × 9/5) + 32. By substituting the value of -77.0 °C, we found that it is approximately -106.6 °F on the Fahrenheit scale.
In part (b), we converted 125 °F to Celsius using the conversion formula C = (F - 32) × 5/9. By substituting the value of 125 °F, we found that it is approximately 51.7 °C on the Celsius scale.
Conversion between Celsius and Fahrenheit scales is essential in various scenarios, especially when dealing with international temperature readings, scientific experiments, and weather forecasts. Understanding these conversions enables effective communication and interpretation of temperature data across different regions and scientific communities.
