(a)

Interpretation Introduction

Interpretation:

From the given possible replacement for CFCs are  HFC-152a and HFC-23, the one which appears to be the better replacement has to be determined by considering only GWP.

Concept introduction:

Global warming is a serious environmental issue, in which there is an increase in the overall temperature of the earth by various factors.

Greenhouse gases are one type of gas which traps the heat within the system and thus it increases the overall temperature of the earth resulting global warming.

Examples: CO2,CH4..

The ability of a trace gas to cause global warming is described by its Global warming potential (GWP) and it is related to the lifetime of a gas in the atmosphere as well as the ability of a gas to absorb IR radiation.

The lifetime of a gas in the atmosphere and its ability of a gas to absorb IR radiation are the two properties which are included in the calculation of the global warming potential

The molar heat capacity of a diatomic molecule is 29.1 J/K · mol. Assuming the atmosphere contains only nitrogen gas and there is no heat loss, calculate the total heat intake (in kJ) if the atmosphere warms up by 3.0°C during the next 50 years. Given that there are 2.8 x 10²20 moles of diatomic molecule present, how many kilograms of ice (at the North and South Poles) will this quantity of heat melt at 0° C? (The molar heat of fusion of ice is 6.01 kJ/mol.) Total heat intake: × 10 kJ Ice melted: × 10 |kg (Enter your answer in scientific notation.)
It is known that carbon dioxide (CO2) emission is responsible for at least 50% of greenhouseemissions. Do we need to be concerned about GWP of CO2 when using it as a refrigerant?What is the ODP of CO2?
1. What are the three main types of greenhouse gases, what are their respective characterization factors or global warming potential? 2. What is meant by the efficiency of a solar panel (PV) and what are the implications for a solar farm? 3. How is energy extracted from wind and what are the implications for a wind farm? 4. For a wind turbine, what is the impact of the wind speed on the electricity production and how does the design of the wind turbine dictate its efficiency? What control strategies can be used to optimise the performance of wind turbines? How can energy be extracted geothermally. Explain how geothermal energy can be utilised to contribute towards heat demand and what is the role of co-produced water. 5. 6.
