Question

The specific heat capacity of copper is  380 J/Kg degree C ,find the final temperature of 2 kg copper ball at 20 degree C, when 4400 J is supplied to the copper ball .

Answer 1

Answer:

Explanation:

we know

Q = heat energy = 4400J

s = specific heat capacity = 380J/KgC

t1 = 20 degree = initial temperature

by applying the formula

Q= msdt where dt =( t2-t1) [t2 is final temperature ]

4400 = 2 x 380 x (t2-20)

4400/(2x380)= t2-20

t2= 4400/(2x380) + 20 will be your final answer after calcuation
