- Description: Imagine you are comparing the five electric hot plates (A – E) of different sizes and temperatures. The temperature of each hot plate is indicated by a shade of gray such that the lighter the shade of gray, the higher the temperature of the hot plate. D B E A A. Ranking instructions: Rank the surface area (from largest to smallest) of the hotplates. Ranking Order: Largest 1 3 4 5 Smallest Or, all the hotplates have the same surface area. (indicate with a check mark) Carefully explain your reasoning for ranking this way: B. Ranking instructions: Rank the temperature (from hottest to coldest) of the hotplates. Ranking Order: Hottest 1 2. 3 4 5 Coldest Or, all the hotplates have the same temperature (indicate with a check mark) Carefully explain your reasoning for ranking this way:What is the name of the specific nuclear fusion process that dominates energy production in the core of the Sun and gives a brief description of how it works. What I'm looking for in this description is what is the basic premise behind nuclear fusion and what is going into this specific fusion reaction and what comes out of it.1 Describe the interieo of the sun. Label and list all the layers. Explain how sun produce energy.
- If the temperature at the centre of the sun is 15,000,000 K and the temperature of the photosphere is 5,800 K, what is the ratio of the temperature at the centre of the Sun compared to the photosphere? Express your final answer in the fully factorised form x : 1, where x is a number that you should determine to an appropriate number of significant figures and write it using scientific notation.62. Pressure of the Photosphere. The gas pressure of the photosphere changes substantially from its upper levels to its lower levels. Near the top of the photosphere, the temperature is about 4500 K and there are about 1.6 x 1016 gas particles per cubic centimeter. In the middle, the temperature is about 5800 K and there are about 1.0 x 10" gas particles per cubic centimeter. At the bottom of the photosphere, the temperature is about 7000 K and there are about 1.5 × 10" gas particles per cubic centimeter. Use the ideal gas law (Mathematical Insight 14.2) to compare the pressures of each of these layers; explain the reason for the trend that you find. How do these gas pressures compare with Earth's atmospheric pressure at sea level?1) What is thermal equilibrium? Is the Sun in thermal equilibrium? How do we know this? 2) In order to maintain thermal equilibrium, how much energy must the Sun generate every second?
