We can’t really answer the question because it’s a drawing however, I can only say the coffee she left in the mug was a liquid that became into a solid depending on how long she left the mug in for. After she took it out and it said it was frozen, if she microwaved it for 1-2 minutes the iced coffee will melt due to the heated waves coming out from the microwave, I don’t know if this will help you or not but mainly ask your teacher
