Water could be made to boil at 105 c instead of 100 c by (1 point) adding a lot of energy to the water increasing the external pressure decreasing the external pressure taking the sample to a higher altitude

Water could be made to boil at 105 degrees Celsius instead of 100 degrees Celsius by taking the sample to a higher altitude. Pressure is directly proportional to temperature. So when you bring water into higher altitude, you are increasing the external pressure and therefore increase the boiling point.

the volume increases
