Heat, Mass, and Temperature Change

“You have 100g of water at 20°C. You add heat to the water until it reaches 30°C. Then, you have 200g of water at 20°C. You add the same amount of heat to this water. What will its final temperature be? Explain your reasoning. You have two identical metal blocks. Block A has a mass of 50g and Block B has a mass of 100g. Both blocks are initially at 25°C. If you add the same amount of heat to both blocks, which block will have a higher final temperature? Explain your reasoning.”
