Find the specific heat of a substance that requires 8000 J of energy to heat up 400g by 20 C?

Explanation:

Given that,

Heat required, Q = 8000 J

Mass, m = 400 g

The change in temperature,

The heat required due to change in temperature is given by :

So, the specific heat of the substance is

question1

1,000 tons

question2

3: 8

question 3

store d
