If you were located at 20 degrees north latitude and 60 degrees west longitude, you would be in water, specifically in the Atlantic Ocean, north of the islands of Antigua and Barbuda in the Lesser Antilles.
Gulf of Mexico
South Pacific Ocean
Water at -20 degrees Celsius; heat will expand matter, so at +40 degrees Celsius, water would have less density. * * * * * That would be true if there were no phase change. Unfortunately for the above answer, water freezes at 0 deg C and that phase change is accompanied by an expansion. As a result, water at 40 deg C is denser that water (ice) at -20 deg C.

Water freezes and becomes ice at zero degrees Celsius. Also, water has the odd quality that it begins to expand below about 4 degrees Celsius. So the answer is that it would turn into ice and its volume would increase a little.
What is the density of water at 37 degrees Celsius?
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.
