Is heat transfer a scalar or a vector quantity? Explain. Answer the same question for temperature.
What will be an ideal response?
Heat transfer is a vector quantity since it has direction as well as magnitude. Therefore, we must specify both direction and magnitude in order to describe heat transfer completely at a point. Temperature, on the other hand, is a scalar quantity.

Studies were conducted at two sites on rural roads with similar characteristics. The first site was 5.1 miles in length with an ADT of 6700. Over the year-long study period, 28 crashes occurred on this portion of roadway, five of them resulting in fatalities. The second site was a 11.2-mile section with an ADT of 5300. There were 32 crashes in this section with four crashes resulting in fatalities. Determine the total crash rate (all types of crashes) and the fatal crash rates for both locations, and discuss the implications.
