Martha is writing a report on the landfill gases near her house. Fill in the blanks to complete her report.
Use this table for calculations:

[tex]\[
T = \frac{m}{f}
\][/tex]

\begin{tabular}{|l|l|l|}
\hline
& Residence Time [tex]$(T)$[/tex] & Mass [tex]$(m)$[/tex] \\
\hline
Methane & 8 years & [tex]$4.3 \times 10^{15}$[/tex] g \\
\hline
\end{tabular}

Landfill Methane

Humans produce a huge amount of waste every day. Landfills were designed to combat this large amount of waste by accumulating and disposing of it. Organic waste from landfills undergoes decomposition in the absence of oxygen, producing gases. Methane gas is a large percentage of the gases emitted from landfills.

If we consider a landfill a reservoir, the flow rate of methane is [tex]$\square$[/tex]. Methane has a longer residence time than [tex]$CO_2$[/tex], and it is a greenhouse gas that traps heat very effectively. Therefore, methane [tex]$\square$[/tex] the temperature of the reservoir.

Sure, let's fill in the blanks of Martha's report based on the provided information.

1. In the first blank, we need to state the flow rate of methane, based on the given data.
2. In the second blank, we confirm the statement about methane's residence time.
3. In the third blank, we describe what methane does to the reservoir's temperature.

Landfill Methane
Humans produce a huge amount of waste every day. Landfills were designed to combat this large amount of waste by accumulating and disposing of it.
Organic waste from landfills undergoes decomposition in the absence of oxygen, producing gases. Methane gas is a large percentage of the gases emitted from landfills.
If we consider a landfill a reservoir, the flow rate of methane is 537,500,000,000,000.0 grams per year.
Methane has a longer residence time than CO2, and it is a greenhouse gas that traps heat very effectively. Therefore, methane increases the temperature of the reservoir.
