Answer:
0.89 J/g/°C
Step-by-step explanation:
The Heat gained by an object is given in terms of specific heat capacity as:
H = mc(T2 - T1)
where m = mass of the object
c = specific heat capacity
T2 = final temperature
T1 = initial temperature
50 g of an unknown metal takes 1112.5 J of energy to change its temperature from 20°C to 45°C.
This implies that:
1112.5 = 50 * c * (45 - 20)
1112.5 = 50 * c * 25
1112.5 = 1250 * c
=> c = 1112.5 / 1250
c = 0.89 J/g/°C
The specific heat capacity of the metal is 0.89 J/g/°C
