Answer:
The specific heat capacity of chromium is 0.449 j/g.°C thus given metal is chromium.
Step-by-step explanation:
Given data:
Mass of metal = 24 g
Initial temperature = 20 °C
Final temperature = 45°C
Energy absorbed by metal = 269.4 j
Which metal is this = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 45°C - 20 °C
ΔT = 25°C
269.4 j = 24 g × c × 25°C
269.4 j = 600 g.°C× c
c = 269.4 j/600 g.°C
c =0.449 j/g.°C
The specific heat capacity of chromium is 0.449 j/g.°C thus given metal is chromium.
