Place the following temperatures in order from coldest to hottest: 20°C, 36°C, 75°F, 94°F

Convert the Celsius temperatures to Fahrenheit using °F = (°C × 9/5) + 32. Then 20°C = 68°F and 36°C = 96.8°F. In increasing order, the temperatures are 68°F, 75°F, 94°F, and 96.8°F, so the correct choice is 20°C, 75°F, 94°F, 36°C.
