why did the first continental congress call for a second continental congress before adjourning?

The First Continental Congress called for a Second Continental Congress before adjourning because the grievances with British policies, specifically the Intolerable Acts, had not been addressed. The First Continental Congress hoped to pressure Britain into repealing these acts through collective colonial action such as boycotts. They agreed to reconvene in the spring of 1775 if their demands were not met, anticipating ongoing conflicts and the need for further united colonial response. This call was part of a plan to organize a stronger, coordinated resistance and to continue efforts to assert colonial rights and manage escalating tensions, which eventually led to the outbreak of the Revolutionary War.
