In the thermite reaction, molten (liquid) iron is produced as a product, and after the reaction is complete, the iron cools and solidifies, eventually coming to thermal equilibrium with the air around it. Calculate the heat change (q) of the iron as it solidifies and cools to the ambient air temperature, using the data below. Mass of Iron Produced 41.97g Maximum Temperature of Thermite Reaction 2300 C Air Temperature 9.44 C Melting Point of Iron 1538 C Heat of Fusion of Iron 247.1 J/g Specific Heat of Solid Iron 0.450 J/g c Specific Heat of Liquid Iron 0.835 J/g C

Juju.01) 5 geologic events a group of students designed an experiment in an ice rink to represent the solar system. the steps of the experiment are listed below. 5: geologic events 1. choose a student to represent the sun. the planets are represented by two tennis balls. 2. ask the student to hold the tennis balls in each palm and spin on the ice with arms stretched out. 3. ask the student to draw in the arms after about 10 spins. 4. observe the student's arms rotate faster when they are closer to the body. 05 geologic events enors) the experiment most likely demonstrates that (2 points) 07 discussion-based sessment/module planets exert gravitational force on the sun the sun exerts gravitational force on the planets 3.07 discussion-based ssessment speed of a planet depends on its distance from the sun new version available!
