Base your answers to questions 1 through 5 on the information below and on your knowledge of chemistry.
Evaluating Gas Stoves
New York State is the first state to institute a ban on stoves and furnaces that are powered by methane gas (CH4 ) in new residential construction. Methane is a greenhouse gas that contributes to climate change.
Leaks from gas stoves and pipelines can be significant. Studies suggest that the warming potential from gas stoves is equivalent to the carbon emissions from 500,000 cars annually. Escaping gas from pipelines can release 6.5 million tons of methane a year. Repairing or replacing pipelines can cost millions of dollars.
A student incorrectly identifies the products of the combustion of methane as oxygen and water. Based on patterns of chemical properties, revise the student’s explanation. [1]
Which gas has similar properties to the fuel being banned in new residential stoves and furnaces?
Greenhouse gases have different global warming potentials (GWPs) due to the amount of each gas present, their ability to absorb energy, and the length of time each gas remains in the atmosphere. The difference between the amount of energy entering Earth’s atmosphere and the amount of energy leaving is defined as radiative forcing. This represents the effect of a greenhouse gas on Earth’s temperature over time.
Natural chemical processes occurring in the soil and air help to remove methane. This reduces the amount of time methane remains in the atmosphere relative to carbon dioxide.
Figures 1 and 2 provide information on selected greenhouse gases, GWP, and radiative forcing.
Choose and support a claim, citing both qualitative and quantitative evidence, to either promote or oppose limiting the use of methane as a way to reduce global warming. [1]
The greenhouse effect is the process that traps heat, which contributes to global warming. One method of addressing global warming is through reforestation. As trees grow, the chlorophyll in leaves helps to remove carbon from the atmosphere. Chlorophyll absorbs electromagnetic radiation that is mostly in the visible part of the spectrum.
Which statement compares the frequency and resulting energy of a photon absorbed by chlorophyll to the frequency and resulting energy of a photon emitted by greenhouse gases?
