Question

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)

Answer 1

Answer: 10.3 pounds of CO₂.

Step-by-step 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:

`10min*30days=(300min)/(month)`

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

`(300min)/(month)*(1h)/(60min)=(5h)/(month)`

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

`1500W*(5h)/(month)=7500W*(1kW)/(1000W)=7.5kW`

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

`7.5kW*(1.37pounds)/(1kW)=10.3pounds`
