Simplifying and taking natural logs on both sides of the equation then brings us to
In 2 = kT1/2
(4)
Use equation 4 and your value for k to calculate another value for T½. Compare it with the
previous value found in point 5 and discuss your results.
The hot liquid magma of molten earth was on full display in Mauna Loa as it has been actively erupting over the past couple of weeks.Geologist and scientist have determined that about 50% of the earth's interior is due to the release of heat by the decay of radioactive elements like potassium-40, uranium-238 and thorium-232, which have half-lives of 1.25 billion, 4 billion and 14 billion years, respectively. a) Write the equation of the BETA-minus decay of potassium-40. b). Write the equation of the ALPHA decay of uranium-238. c). Write the equation of the ALPHA decay of thorium-232.
Energy release Consider these three events:
(1) On May 18, 1980, the volcanic eruption of Mount
St. Helens in Washington released approximately
1.7 X 1018 joules of energy.
(2) When a 1-megaton nuclear bomb detonates, it releases
about 4 X 1015 joules of energy.
(3) The 1989 San Francisco earthquake registered 7.1 on
the Richter scale.
(a) Make some comparisons (i.e., how many of one event
is equivalent to another) in terms of energy released.
(Hint: Refer to Exercise 70 in Chapter 5 Review Ex-
ercises.) Note: The atomic bombs dropped in World
War II were 1-kiloton bombs (1000 1-kiloton
bombs = 1 1-megaton bomb).
(b) What reading on the Richter scale would be equivalent
to the Mount St. Helens eruption? Has there ever been
a reading that high?

There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star.

Plants capture the energy when growing, and then through a long process of decay and compression this plant matter is converted into a fossil fuel. An interesting question is how much sunlight is needed to produce a quantity of petrol. To estimate this, let's assume the petrol has come from wood, and let's assume we have a fast-growing wood source such as Pinus radiata. Assume also: a mature tree contains around 3 m3 of timber; a tree is harvested when 35 years old; the density of wood is around 500 kg/m3; 2 kg of wood makes 1L of petrol; a tree receives on average 8 hours of sunlight per day. How many "hours of sunlight" are stored in 1L of petrol? i.e. how many hours of sunlight does a tree need to be exposed to, to produce the amount of wood needed to make 1 L of petrol?
