How much carbon dioxide is produced from running a microwave (1500 watts) for 10 minutes per day for one month? (round to the tenths place)

Respuesta :

Answer: 10.3 pounds of CO₂.

Explanation

Assuming that we have 30 days in a month, we are told that a microwave is turned on for 10 minutes each day for one month.

0. We have to calculate the minutes of the month that the microwave is turned on:

[tex]10min\times30days=\frac{300min}{month}[/tex]

Then, the microwave is turned on 300min per month. If we convert this to hours we get:

[tex]\frac{300min}{month}\times\frac{1h}{60min}=\frac{5h}{month}[/tex]

2. Also, we have to calculate the watts that are used per month, meaning that:

[tex]1500W\times\frac{5h}{month}=7500W\times\frac{1kW}{1000W}=7.5kW[/tex]

3. Finally, assuming that 1.37 pounds CO₂ are produced per kW:

[tex]7.5kW\times\frac{1.37pounds}{1kW}=10.3pounds[/tex]
