When a liquid is boiling that means it has gotten heated to the point where the oxygen particles start rising towards the top of the liquid.
When a liquid has a temperature (as it always will) it can be read, however, a liquid does not need to be hot to have a temperature.
A liquid requires an extremely high level of heat (thermal energy) to begin boiling, while a liquid doesn't require any heat to have a temperature.
The difference between the two is that boiling requires high heat and a temperature doesn't require heat (That is 3 total the ones above count).
Hope this helps and have a nice day.
