What a strange question. You've given the units for the degrees in the second part, but not the first. So I assume they are both the same units (F). In which case how about adding 20 to 52 and getting 72?
20 degrees warmer than -10 degrees would be 10 degrees.
20 degrees warmer than -10°C is 10°C.

The temperature in direct sunlight can be as much as 20-30 degrees Fahrenheit warmer than in the shade, due to the absorption of heat from the sunlight.

72 is 20 warmer than 52.

The future temperature of the water depends upon the surrounding air's temperature. So if the air around the test tube is colder than 20 degrees, then the water will get colder. If the air temperature is warmer than 20 degrees then the water will get warmer.
The temperature at 20 degrees north is warmer than at the Equator due to the tilt of the Earth's axis. At 20 degrees north, the tilt causes this region to receive more direct sunlight and experience a stronger heating effect, resulting in higher temperatures compared to the Equator.

20 Celsius is colder than 25 Celsius. The higher the number in degrees Celsius, the warmer the temperature.
