Explain all answers clearly, with complete sentences and proper essay structure if needed. An asterisk (*) designates a quantitative problem, for which you should show all your work.
Internal vs. External Heating. Earth’s internal heat leaks out through the surface with a power of about 3 trillion watts. Divide this amount by Earth’s total surface area to find the rate of heat loss per square meter. Compare your result to the amount of power contributed by sunlight, which provides an average of about 400 watts square meter in daylight.

Perform the following calculation and round the answer to the correct number of significant figures. Use the formula editor to show your work. 2(1.008 /mol) + 15.99 8/mol NOTE: Recall that we only consider the number of significant figures given in measured values. In this case, the 2 was not measured. Therefore we are only interested in the significant figures of 1.008 %/mol and 15.99 %/mol.

- Answer the following questions and be sure to show all your work. a. It is difficult to extinguish a fire on a crude oil tanker, because each liter of crude oilreleases 2.80×10^7 J of energy when burned. To illustrate this difficulty, calculate thenumber of liters of water that must be expended to absorb the energy released byburning 1.00 L of crude oil, if the water has its temperature raised from 20.0ºC to 100ºC,it boils, and the resulting steam is raised to 300ºC.b. Discuss additional complications caused by the fact that crude oil has a smaller densitythan water.arrow_forwardA balloon, in the shape of a right circular cylinder, is being inflated in such a way that the radius and height are both increasing at the rate of 3 cm/s and 8 cm/s, respectively.

- Instructions: Your task is to create a model in response to the prompts in the question below. Be sure to apply a model from this class and include the relevant diagram(s) for that model. And don’t forget to use the Claim, Evidence, Reasoning framework to present your solution. Phenomenon: Runaway Truck Ramp A truck was driving on a highway at 30 m/s when its brakes gave out. The driver steered it onto a “runaway truck ramp”, consisting of an upward ramp (rising 12 meters vertically over 120 meters horizontally), and ending with a compressible barrier which you can model as a giant spring with spring constant “k”. The compressible barrier can be compressed by a maximum 0.5 meters before it stops working. Graphic attached Values: Mass of the truck: 20 metric tons (1 metric ton = 1000kg). Mass of the driver: Choose a reasonable value. Truck Ramp Dimensions: 12 meters vertical, 120 meters horizontal Spring constant k= 6.0 x 107 J/m2. Part 1: Big…arrow_forwardProblem 2.

I already solved part a) 1)Energy Efficiency at Home : Suppose you have two kettles – a plug-in electrickettle and a stovetop kettle. The electric kettle uses electricity from a natural gas fired powerplant, while you boil water in your stovetop kettle on a natural gas burner. a)Based on the following information, which of these kettles demonstrates a higher energy efficiency (i.e., which is more efficient at using energy from fuel to heat water)? Please calculate the efficiencies of each kettle and express answers as percentages. -The natural gas power plant converts chemical energy of the natural gas to electrical energy with 58% efficiency. -High-voltage power lines from the power plant to your house convey electricity with 92% efficiency. -The electric kettle converts electrical energy to thermal energy in the water with 85% efficiency (the other 15% heats up the kettle itself). -The stove…arrow_forwardComplete the questions below using additional paper if needed.
