1. Convert -450 degrees Fahrenheit to Celsius. The Correct Answer and Explanation is: Answer: To convert −450 degrees Fahrenheit to degrees Celsius, we use the formula:°C=59(°F−32)°C = \frac{5}{9} (°F – 32)°C=95​(°F−32) Substituting −450 for °F:°C=59(−450−32)=59(−482)=−267.78∘C (rounded to two decimal places)°C = \frac{5}{9} (-450 – 32) = \frac{5}{9} (-482) = -267.78^\circ C \, (\text{rounded to two decimal places})°C=95​(−450−32)=95​(−482)=−267.78∘C(rounded to two decimal places) Explanation: Temperature conversion

Convert the pressure 1.30 atm to kPa The Correct Answer and Explanation is: Conversion of Pressure: To convert 1.30 atm (atmospheres) to kPa (kilopascals), use the conversion factor:1 atm=101.325 kPa1\ \text{atm} = 101.325\ \text{kPa}1 atm=101.325 kPa So,1.30 atm×101.325 kPaatm=131.7225 kPa1.30\ \text{atm} \times 101.325\ \frac{\text{kPa}}{\text{atm}} = 131.7225\ \text{kPa}1.30 atm×101.325 atmkPa​=131.7225 kPa Answer:1.30 atm=131.72 kPa(rounded to two decimal places)1.30\ \text{atm} = \boxed{131.72\ \text{kPa}} \quad \text{(rounded to two decimal places)}1.30 atm=131.72 kPa​(rounded to two decimal places) Explanation: Pressure is defined
