A substance has a triple point at a temperature of 17 ∘C and a pressure of 3.2 atmospheres. In what states can the substance exist on the surface of Earth at sea level (open to the atmosphere)?

The states of matter can be classified under the three phases of the states, these are defined as,

1) Gas

2) Liquid

3) Solid

The substance when with a triple temperature point at the given conditions:

If the pressure of the land at sea level, we will have the characteristics of

Therefore, the substance can exist in the solid or gas phase because here the pressure decreases and the temperature increases more than the triple point.

the answer would be   dignified - apex
