A 4.0 g sample of a solid changes from 20.0 ºC to 36.0 ºC upon addition of 25.0 cal of heat. What is the specific heat of this s olid?
1 answer:
Answer: c = 0.39 cal/g°C or
1.63 J/g°C
Explanation: To find the specific heat of the metal we will use the formula of heat which is Q= mc∆T.
We will derive for c, c = Q / m∆T
25.0 cal/ 4.0 g ( 36°C - 20°C)
= 0.39 cal / g°C
Or we can convert calories to joules.
0.39 cal x 4.184 J/ 1 cal
= 1.63 J /g°C
