Chapter 1, Problem 34c,d,e
(c) During winter, the temperature of the Arctic region can drop below -50 °C, what is the temperature in degree Fahrenheit and in Kelvin? (d) The sublimation temperature of dry ice is -78.5 °C. Convert this temperature to degree Fahrenheit and Kelvin. (e) Ethanol boils at 351 K. Convert this temperature to degree Fahrenheit and degree Celsius.
Verified step by step guidance1
To convert from Celsius to Fahrenheit, use the formula: \( F = \frac{9}{5}C + 32 \). For part (c), substitute \(-50\) for \(C\) to find the temperature in Fahrenheit.
To convert from Celsius to Kelvin, use the formula: \( K = C + 273.15 \). For part (c), substitute \(-50\) for \(C\) to find the temperature in Kelvin.
For part (d), use the same formulas as in part (c) to convert \(-78.5\) °C to both Fahrenheit and Kelvin.
To convert from Kelvin to Celsius, use the formula: \( C = K - 273.15 \). For part (e), substitute \(351\) for \(K\) to find the temperature in Celsius.
To convert the Celsius temperature obtained in part (e) to Fahrenheit, use the formula: \( F = \frac{9}{5}C + 32 \). Substitute the Celsius value you calculated to find the temperature in Fahrenheit.

Textbook Question
(a) A sample of tetrachloroethylene, a liquid used in dry cleaning that is being phased out because of its potential to cause cancer, has a mass of 40.55 g and a volume of 25.0 mL at 25 °C. What is its density at this temperature? Will tetrachloroethylene float on water? (Materials that are less dense than water will float.)

(b) Carbon dioxide (CO2) is a gas at room temperature and pressure. However, carbon dioxide can be put under pressure to become a 'supercritical fluid' that is a much safer dry-cleaning agent than tetrachloroethylene. At a certain pressure, the density of supercritical CO2 is 0.469 g/cm3. What is the mass of a 25.0-mL sample of supercritical CO2 at this pressure?
