Heat energy required to change the temperature is given by

$Q = ms\Delta T$

here we know that

$m = 225 g = 0.225 kg$

$s = 4186 J/kg C$

$T_i = 5 ^0C$

$T_f = 35 ^0C$

now from above formula we will have

$Q = (0.225 kg)(4186 J/kg C) (35 - 5)$

$Q = 28255.5 J$

So it will remove 28255.5 J heat from the water

Tju [1.3M]

Every organism may classified into seven level of classifications, such that each level contains organisms with similar characteristics. Kingdom is the largest and the broadest level of classification while species is the smallest and most specific level of classification. Therefore from the largest to the smallest the order is as follows:
Kingdom
Phylum
Class
Order
Family
