ASAP please will mark as brainlist don’t got much time

question 4. 69.19J

question 5. 40835.84J

Explanation:

question4.

heat needed = mass × specific heat capacity × change in temperature

= 9.3× 0.240×(52-21)

=69.192J

question 5.

heat added = 160× 4.184×(85-24)

= 40835.84J

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
