Answer: The specific heat of the liquid is 
Explanation:

As we know that,

.................(1)
where,
q = heat absorbed or released
= mass of glass = x kg
= mass of liquid = x kg
= final temperature =
= temperature of glass = 
= temperature of liquid = 
= specific heat of glass = 
= specific heat of liquid= ?
Now put all the given values in equation (1), we get
![-[(x\times 840\times (53-83)]=x\times c_2\times (53-43)](https://tex.z-dn.net/?f=-%5B%28x%5Ctimes%20840%5Ctimes%20%2853-83%29%5D%3Dx%5Ctimes%20c_2%5Ctimes%20%2853-43%29)

Therefore, the specific heat of the liquid is
