How much solar energy (kJ) would have to be transferred to a 154.0 foot length of asphalt highway that is 43.0 feet wide and 21.7 centimeters deep in order to raise the temperature 1.00 oC ?
The average density of asphalt is 721 kg/m3
The specific heat of asphalt is 0.920 kJ/kg-oC
first, I found the volume, and then I found the mass. Then I used the equation q=(c)(m)(change in temp.) and got the answer as 4.96872 but it’s not the right answer…
help please?
okay, I got it now. thankss =]
