Suppose your thermometer is off by 1.5 oc i. e. it reads values that are 1.5 oc higher. how would this affect the results in this experiment? (3 pts)

I assume that the experiment is about calculating the enthalpy of a reaction. 
If you consistently use the thermometer for all procedure in the experiment, the effect will be negligible because all temperature will be increased by 1.5 °C.

In enthalpy calculation, the energy is determined by the temperature differences. If the final and initial temperature increased by 1.5 °C, then the difference will not be changed.

That result from subduction of oceanic plates beneath lighter continental plates. most of the earth's volcanoes are located around the pacific ring of fire because that the location of most of the earth's subduction zones.
