1. To find Fahrenheit temperature for -20 degrees Celsius, you can just plug it into the formula. Therefore, F = 9/5 (-20) + 32 and F = 28.4.5

2. Carbon dioxide has no liquid phase at atmospheric pressure. Solid CO 2 is known as dry ice because instead of melting, it sublimes. Its sublimation temperature at atmospheric pressure is −78 ° C

3. Answer: 38.61

Explanation: C= (5/9)(101.5-32)

=38.61 C
