Question

How much carbon dioxide is emitted from using a 1500 watt dryer for 8 hours every
week for 1 year? (Assume 1.37 pounds of CO2 is produced per KWH of electricity
used). (round to the hundredths place and do not include the unit)

Answer 1

9514 1404 393

Answer:

  854.88 lb/yr

Step-by-step explanation:

It is effectively a units conversion problem. The conversion factors of interest are ...

  1000 W × 1 h = 1 kWh

  52 wk = 1 yr

__

  (1500 W)×(8 h/wk) × (52wk/yr) ÷ ((1000 W)(1 h))/(1 kWh) × (1.37 lb/kWh)

  = (1500×8×52×1.37)/(1000) lb/yr

  = 854.88 lb/yr
