3. Which is greater 50 °C or 50 °F?
Answer (1)
Answer:Here are the answers to your questions: 1. Units of Temperature: - Celsius (°C): The Celsius scale is the most commonly used temperature scale in the world. It is based on the freezing point of water at 0°C and the boiling point of water at 100°C.- Fahrenheit (°F): The Fahrenheit scale is primarily used in the United States. It sets the freezing point of water at 32°F and the boiling point at 212°F.- Kelvin (K): The Kelvin scale is the standard unit of temperature in the International System of Units (SI). It is an absolute temperature scale, meaning that 0 K represents absolute zero, the lowest possible temperature.2.

Conversion of Temperature: 1. Boiling Point of Chlorine: - Fahrenheit: - Formula: °F = (°C × 9/5) + 32- Calculation: °F = (34°C × 9/5) + 32 = 93.2°F- Kelvin: - Formula: K = °C + 273.15- Calculation: K = 34°C + 273.15 = 307.15 K 2. Air Temperature in Celsius and Kelvin: - Celsius: - Formula: °C = (°F - 32) × 5/9- Calculation: °C = (83°F - 32) × 5/9 = 28.33°C- Kelvin: - Formula: K = °C + 273.15- Calculation: K = 28.33°C + 273.15 = 301.48 K 3. Comparing 50°C and 50°F: - 50°C is greater than 50°F. You can see this by converting 50°F to Celsius:- °C = (50°F - 32) × 5/9 = 10°C- Therefore, 50°C is much warmer than 50°F.
