Materials for the construction of an amusement park are being considered for the building of various rides and attractions at the park. Materials are being selected based on their specific heat and are listed in the table below.
Material
Specific
Heat
(J/(kg•K))
450
900
Iron
Aluminum
Steel
502
Glass
840
2302
Plastic
The formula that relates energy change, mass, specific heat, and temperature change is
Energy Change = Mass Specific Heat Temperature Change
The amusement park will be located in a hot climate. The engineers want to select a material for the giant slide that will prevent the surface from
getting too hot. Based on the specific heat values, what material would be the best choice?
A plastic, because it takes more energy to raise its temperature
B. iron, because it takes more energy to raise its temperature
C. plastic, because it takes less energy to raise its temperature
Diron, because it takes less energy to raise its temperature

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
