The car travels at an average speed of 60 mph the entire way.

The parameters are as follows:

t = 1.75 hours for the car's motion;

[tex]x_{1}[/tex] = 10 miles for its initial position, and

[tex]x_{2}[/tex] = 115 miles for its final position.

The following formula is used to determine the car's overall mileage:

Distance traveled =[tex]x_{2} -x_{1}[/tex] = 115 miles - 10 miles = 105 miles

Thus, the distance traveled is 105 miles.

The following formula is used to determine the vehicle's average speed during the entire journey:

Average Speed = Distance traveled/Time Taken

The original temperature of the mercury was 236k

Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius. Temperature indicates the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature).

Total energy needed to crystallize mercury = F = heat of fusion = 11.3 kJ/kg ×7 kg = 79.1 KJ.

Let Q = Total Heat released - F = 81.06 kJ -  79.1 kJ = 1.96 kj.

Then, Q=ФMC

Ф =Q/MC

Ф =1.96kJ/(7kg*0.14kJ/ kgK)
