Final answer:
The boiling point of water can vary based on pressure. In the student's experiment, the water did not begin boiling until 105°C, indicating that the pressure may have been higher than 1 atm.
Step-by-step explanation:
The boiling point of water is normally 100°C at sea level, but it can vary based on the pressure. When the pressure is higher than 1 atm, the boiling point of water increases. In the student's experiment, since the water did not begin boiling until 105°C, it suggests that the pressure in the experiment may have been higher than 1 atm.
