Can someone please answer these questions. Here is the simulation that is use if that helps. https://phet.colorado.edu/en/simulation/energy-forms-and-changes
4. When you added the iron to the water, you saw a rise in temperature from 25 C to 47 C. If the amount of energy delivered to the water from the iron was 1100 j, what was the mass of the water in the beaker? Use specific heat of water as 4.2 j/gC.
5. How much energy would it take to covert the mass of that water from # 1 from room temperature to steam at 100 C?
6. Using the same mass of water, calculate the total energy needed to vaporize the water to 120 C from an ice cube at -20 C.
7. In the Energy systems tab of the lab, suppose the steam from the teapot that’s turning on the lightbulb is 100 C. If the mass of the steam coming out is 2.76 g, how much heat would you have to remove from the system to get the lightbulb to go out?
