Sn Zn H₂O 0.213 0.387 4.186 5. If you have 50.0 g samples of each of the various metals and water, and you add 100 J of energy to each, which substance will have the largest resulting temperature change? Which substance will have the smallest temperature change? Explain A. Maystry et al. 6. The following errors would cause a change in the calculated specific heat capacity for your metals. Explain how each change would affect the calculated valu of the specific heat capacity of your metals. a. The metal "cools off" as you transfer it from the hot water to the calorimeter. b. The calorimeter loses heat to the surroundings as you are stirring. HCHS Chemistry Lab Exercise #19: Specific Heat Capacity and Calorimetry Page 4 of 5

Below are 3 real life situations. Pick two (2) them and explain ALL the science involved in the scenario. This means describe things like what is happening to the gas/liquid/solid molecules or atoms, which principles or laws are at work, why what is happening is happening, and how you know.  At sea level, a pot of water will boil at 100 °C. Suppose you wanted to boil the same amount of water high in the Rocky Mountains. What do you expect the temperature will need to be (generally speaking)? Why?   A can of soda sits in a sunny spot on the window sill for several hours. It is then opened at the same time as a cold can of soda from the refrigerator. What happens and why?   Weather balloons do not float out into space. They reach an altitude of about 15 miles above the surface (3x the height of Mt Everest) and they burst. Why?

can i get help, i thought this was the answer and its not

4) The intensity of gamma rays, X-rays, or any other radiation is A) inversely proportional to the cube of the distance from the source. B) inversely proportional to the distance from the source. C) inversely proportional to the square of the distance from the source. D) directly proportional to the square of the distance from the source. E) directly proportional to the distance from the source. dele (1
