How much CO2 is produced from ironing clothes for 1.4 hour a week for 3 weeks? Round you answer to the nearest tenth.

 

Answer:

Find the total energy consumed on ironing clothes and then multiply it by factor 0.92 which is ?CO2?? produced per ?kwh? energy.

The average rating of electric iron is ?1100? watts

In a week, it consumes ?=1100∗1.4/1000?? ?=1.54? ?kwh? of energy

In three weeks it consumes ?=1.54∗3=4.62? ?kwh? of energy

Now, ?1? ?kwh? energy produces ?0.92? pounds of ?CO2??

?4.62? ?kwh? energy produces ?=4.62∗1.54=4.3? pounds of ?CO2??
