Hello, this is my first time visiting this forum and I hope someone can help me with my Physics homework. This is the problem: Your pet fish (Pythagoras) lives in a bowl that holds 4000 ml. of water. The temperature of the water must be at 30° C or Pythagoras will die. Unfortunately, you only have two sources of water. One source of water is at 90° C and the other source of water is at 10° C. Your goal will be to determine how much of each source of water must be added to the bowl so that it contains 4000 ml of 30° C water (so that Pythagoras will live). Thanks in advance for any help!!
