Below is a screenshot from a YouTube video where a guy named Hans is simultaneously running the heaters of two Tesla Model 3's on a cold day. The descriptions in this problem worksheet are realistic according to what Hans describes in the video. The car on the left is a 2021 model, and the car on the right is a 2019 model. The 2019 Model has Tesla's older heating system installed. The older system is called a \"resistive\" heater, and it works by directly converting electrical energy from the battery into thermal energy on the inside of the car by heating up a piece of metal and then blowing hot air past it. Since the input electric energy is converted directly into thermal energy, the COP of this resistive heating system approximately equals 1. By contrast the 2021 model has a heat pump system installed which, as we've discussed already in the course, works by transporting heat from the outside of the car to its inside. The heat pump in the 2021 car operates at r0ughly 18% of its theoretical maximum coefcient of performance (COP) given the temperatures on the inside and outside of the car. In the video, Hans does a test where the cars are both maintaining a temperature of 70F on their interiors. Over a 1-hour period, the 2019 model uses 2.17 kWh of the car battery's energy while the 2021 model uses 0.74 kWh. 1. Presumably Tesla moved from resistive heaters in their cars to heat pumps because the heat pumps are more efficient. Is this the case based on the test Hans performed? By what factor did the COP change? Hint. Consider the ratio of COP's of the heaters in the two cars, and assume that they require the same heat to be pumped in to keep the car at 70 F. This assumption is reasonable since they are pretty much the same car except for their heating systems.2. What is the temperature of the air Outside the cars in degrees Fahrenheit? 4020 EW 65050
