Determine the final temperature of a gold nugget (mass = 376 g) that starts at 398 K and loses 4.85 kJ of heat to a snowbank when it is lost. The specific heat capacity of gold is 0.128 J/g°C.

Final temperature of a gold nugget will be 297 K

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

q = heat released  = -4.85 kJ = -4850 J

m = mass of metal =  376 g

= final temperature of metal = ?

= initial temperature of metal = 398 K

c = specific heat of metal =

Thus the final temperature of a gold nugget will be 297 K

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
