Hello! if anyone could help me with three questions that would be great. I ask to please answer in a way a highshcooler can understand. Also question 3 is attached along with the graph for the 2nd question if it doesn’t show up when I posted. Handwritten or typed is fine.

  1. A 200.0 g copper block absorbs 2.34×10^3 J of heat to raise its temperature by 30.0 K. What is the specific heat of copper? Show your work.

  1. A 500.0 g metal block absorbs 3.25×10^3 J of heat to raise its temperature by 50.0 K. What is the substance? Show your work.
