It is widely accepted that a meteor impact 65 million years ago caused a mass extinction of life on our planet, relegating the dinosaurs to the fossil record. The meteor was about 5 miles in diameter and moving at about 20 miles per second relative to the earth. Assume the density of the meteor was similar to that of the earth, about 5.5 g/cm³. (a) The meteor was vaporized during the impact and virtually all of its kinetic energy was converted into heat. How much energy was released as heat? Report your result in joules (J). (b) This was an inelastic collision: (The meteor ended up as a layer of dust about half an inch thick covering the entire planet.) How much did the velocity of the earth change as a result of the impact?

A balloon is slowly heated so that the pressure does not change. If it was initially at 10 K and had a volume of 50 m3, what will the new volume be when heated to 70 K?
A habitat on Mars uses silicon solar panels that absorb heat from the sun, resulting in an increase in temperature only during times of sunlight. A silicon solar panel absorbs 68,750 calories per hour [cal/h] from the sun. Calculate the change in temperature in degrees Fahrenheit [°F] of the panel in three hours [h] if the panel has a mass of 175 kilograms [kg]. Note the specific heat of silicon is 0.7 joules per gram degree Celsius [J/(g °C)].
Consider a planet where Solar onstant = 1360 W /m2 and albedo=0.30. If the planet has a water vapor feedback so that the number of layers n is a function of surface temperature nT = (T – 254.5)/100, what is the equilibrium surface temperature?
The sun doesn't shine as brightly in winter as it does in summer. This means that in winter you won't generate enough to fulfil your energy needs whilst you have a surplus of energy in summer. It is therefore necessary to place a battery in your house to store the extra energy. If we assume that we generate 66% of our total energy in the months April to September and that we use equal amounts of energy throughout the year. Question: How much electricity must we store over these 6 months to use in the other half of the year? Give your answer in 3 significant figures (link). Remember we use 2990 kWh of electricity per year. Write down your answer as you need it for the next question Solution: kWh
A habitat on Mars uses silicon solar panels that absorb heat from the sun, resulting in an increase in temperature only during times of sunlight. A silicon solar panel absorbs 68,750 calories per hour[cal/h] from the sun. Calculate the change in temperature in degrees Fahrenheit [°F] of the panel in four hours [h] if the panel has a mass of 205 kilograms [kg]. Note the specific heat of silicon is 0.7 joules per gram degree Celsius [J/(g °C)]. Part 2 The change in temperature is °F. (Round your answer to one decimal place.)
If a nonhuman civilization were to develop on Saturn's largest moon, Titan, its scientists might well devise a temperature scale based on the properties of methane, which is much more abundant on the surface than water is. Methane freezes at -182.6 °C on Titan, and boils at -155.2 °C. Taking the boiling point of methane as 100.0 °M (degrees Methane) and its freezing point as 0 °M, what temperature on the Methane scale corresponds to the boiling point of water on the Celsius scale, 100 °C? You must show all of the conversion steps.
I have a bucket of icewater with 100 grams of ice and 900 grams of liquid water all at zero degrees Celcius. I throw a hot chunk of iron into it (after which no heat enters or escapes the system), and the final temperature is 100 degrees Celcius with the ice having melted and some of the water actually boiling. The mass of the iron is 473 grams, and its initial temperature is 7,646 degrees Celcius. How many grams of water actually boil? (Don't write the unit, just the number.) You'll need these numbers: Specific heat of water: 4.2 J/g/deg Specific heat of iron: 0.46 J/g/deg Heat of fusion of water: 340 J/g Heat of Vaporization of water: 2300 J/g
The Sun delivers radiant energy to Earth at a rate that averages approximately 1.3kW per square metre of the cross-sectional area of Earth. If we assume that all ofthis energy is absorbed by Earth (i.e., that Earth has an emissivity of one), at whatrate must Earth radiate energy if Earth’s temperature is to remain constant? Whatwould that constant temperature be? (Note: The actual temperature of Earth issomewhat higher due to the greenhouse effect of the atmosphere.)

The average temperature of the Earth's surface is estimated to be around 15°C (59°F). However, due to climate change, this temperature is increasing by approximately 0.2°C (0.36°F) every decade. Assuming this trend continues, what will be the average temperature of the Earth's surface in 50 years?
