- serature rennelt and Ke (3) A Celsius thermometer indicates a temperature of -40°C. (a) What Fahrenheit and Kelvin temperatures correspond to this Celsius temperature? (b) If the temperature changes from -40 °C to +10°C, find the change in temperature on the Fahrenheit scale.Notice that the difference between the freezing and boiling point of water is 180 degrees in the TEMPERATURE (°C) symbol (*), followed immediately by either C or F (no spaces). On the Fahrenheit scale: O°F 32°F freezing point of water (equivalent to 0°C) 212°F boiling point of water (equivalent to 100°C) Fahrenheit scale (32°F....212°F) but is 100 degrees in the Celsius scale (0°C..T00 C). As with using the metric system, it is important in the sciences to learn to use and report temperature readings using the Celsius scale since it is more universally used than the Fanrenniore scale. The formulas used to convert between these two temperature scales are listed below. When converting from°F to°C °C= ('F - 32) 1.8 °C=5/9('F - 32) -OR- When converting from°C to°F °F = (°C x 1.8) + 32 °F = (°C x 9/5) + 32 -OR- Use the above equations (either the decimal or fraction form) to complete the following conversions. Space is provided should you wish to write out your work. Place your answer (and…Why is it necessary to specify the temperaturewhen making a table listing ∆G values?
