Question

multiple - choice question
why is it dangerous to heat a closed container?
the pressure created inside the container can burst it
the chemicals will react oddly under the increased heat and pressure
the chemicals inside will not be able to boil

Explanation:

When a closed - container is heated, the gas or liquid inside expands. Since there is no outlet for the increased volume, pressure builds up. High pressure can cause the container to burst. The second option is less likely as it implies a chemical - specific reaction rather than a general physical principle, and the third option is incorrect as heating can cause boiling.

Answer:

The pressure created inside the container can burst it
