2-) Calculate the resulting CO2
concentration in the atmosphere 30 years
from now assuming that we will use only
coal to generate electricity. Assume
efficiencies of 40 % for power plants. The
current CO2 level in the atmosphere is 370
ppm by volume. Assume that all of the
atmosphere's mass is within 11 km of the
planetary surface. Is this a reasonable
value? If it is not, state some reasons. State
all your assumptions.

4. Wind chill describes the additional cooling that occurs when skin is exposed to wind.
The equation is W(v)=-0.17v³+18.4v²-584v-239 for 0 ≤ v ≤ 45, where v is the wind speed
in metres per second. The units for W are megajoules per square metres per hour.
Determine the speed of the wind that gives a minimum wind-chill factor.

Part A
Estimate how many large maple trees would be needed to run a dishwasher for one year. Assume the dishwasher uses
1.1 x10 J of energy per year and a large maple tree captures 10 kg of carbon (in CO2) per year. Assume the power
plant that generates the electricity is 35 % efficient at converting the carbon in coal to electrical energy and that typical
coal releases 40,000 kg of carbon (as CO2) per terajoule of energy when burned.

Thermal energy storage is a proposed method to store solar energy in between use. This technology works by focusing solar arrays to heat up a molten salt (usually a mix of Na+/K+/Li+/NO, ). Then the energy from the molten salt can be used later to run a steam generator and produce work. a) Suppose 10,000 tons of molten salt have been heated up to 800K (1 ton 907 kg). This molten salt has a heat capacity of 1.5 J/g/K. How much heat is released from the salt when it is cooled to 550 K? b) Now suppose all of this heat is used to heat up water. What volume of water can be heated from room temperature to 100°C using the heat released from the salt? 6:37 1/29/ Home End Insertarrow_forward
