If 950 joules of heat are needed to increase the temperature of 45.6 grams of an unknown metal from 25.0 celsius to 90.0 celsius, what is the specific heat capacity of the metal in j/g celsius

0.321 J/g.°C.

Explanation:

Q = mcΔT,

Where, Q is the amount of heat needed to raise the temperature of the metal (Q = 950 J).

m is the mass of the metal (m = 45.6 g).

c is the specific heat capacity of the metal (J/g.°C).

ΔT is the temperature difference (ΔT = final T - inital T = 90.0 °C - 25.0 °C = 65 °C).

∴ c = Q / mΔT = (950 J) / (45.6 g)(65  °C) = 0.321 J/g.°C.

c)red bank

explanation:

red bank is a borough in monmouth county, new jersey, incorporated in 1908 and located on the navesink river, the area's original transportation route to the ocean and other ports.
