So if they fall, the padding will protect their neck or body part so they will not hit hard against the hard wooden or tile floor.
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
