Post Lecture Homework Chapter 06 hET Simulation Energy Forms and Changes 40113 ▼ Part B In the PhET simulation window, click the Energy Systems tab, check the "Energy Symbols" box in the upper right, and use the simulation to recreate the illustrated energy conversion processes. Observe the forms of energy as they are converted and correctly identify the energy conversions for each Drag the appropriate systems to their respective targets View Available Hint(s) Reset Help Mechanical Electrical energy →Thermal energy Light energy → Electrical energy → Thermal energy → Light energy energy energy → Electrical energy → Thermal energy → Light energy energy-yRechanical energy → Electrical energy → Light energy Submit Heat capacity Heat capacity refers to how much energy a material can absorb with respect to changes in average kinetic energy, and its specific heat capacity quantifies the exact amount of energy it takes to raise 1 g of the material's temperature by 1 c (depending on the units, which can sometimes refer the moles of material). Heat capacity refers to the temperature changes in the same state of matter, whereas the per unit energies required to melt and boil a substance are called the enthalpies of fusion and vaporization, respectively The relationship between heat and temperature change is described by the following equation m,AT where q is the heat absorbed or lost, m is the mass, c, is the specific heat, and sr is the change in temperature ▼ Part C Suppose 1 kg each of water (4.19 J/g-°C), brick (0.90 J/g-c), iron (0.46 J/g.°C), and plastic (1.01Jc) were held at the same initial temperature and heated for an equivalent amoun of time. Indicate the relative final temperatures by ordering from lowest to highest resulting temnerature if usinn the Intro tah of the PhET to heln vicualize the temnerature changes
