Question

what state/phase is the object likely from points a to b? options: solid, liquid, plasma, gas

Explanation:

In a heating - curve graph (the type of graph shown, with time on the x - axis and temperature on the y - axis), the first segment (from A to B) typically represents the heating of a solid. As heat is added, the temperature of the solid increases. In later segments, flat parts represent phase changes (like melting or boiling), and subsequent sloped parts represent heating of the liquid or gas. So from A to B, the object is in the solid state.

Answer:

Solid
