Question

When a hydrocarbon fuel is burned, almost all of the carbon in the fuel burns completely to form co2 (carbon dioxide), which is the principal gas causing the greenhouse effect and thus global climate change. on average, 0.59 kg of co2 is produced for each kwh of electricity generated from a power plant that burns natural gas. a typical new household refrigerator uses about 700 kwh of electricity per year. determine the amount of co2 production that is due to the refrigerators in a city with 200,000 households?

Answer 1

Answer:- 82600000 kg of carbon dioxide is produced per year.

Solution:- Given info is as follows:

0.59 kg of carbon dioxide is produced for each kwh of electricity generated in a gas power plant.

One house hold refrigerator uses 700 kwh of electricity per year.

We need to calculate the amount of carbon dioxide produced due to refrigerators in a city with 200000 households.

We can solve this problem easily using dimensional analysis as:

$200000 Refrigerators(\frac{700 kwh}{1 refrigerator})(\frac{0.59 kg CO_2}{1 khw})$

= 82600000 kg of carbon dioxide
