Answer:
136000 J or 136 kJ
Explanation:
Formula
Heat = m * c * deltaH
Givens
m= 0.5 kg
c = 3400 J / (kg * oC)
Deltat = (100oC - 20oC)
deltat = 80oC
Solution
Heat = 0.5 kg * 3400 J/(kg* oC) * 80oC
Heat = 136000 Joules
Heat = 136 kg
Technically there is only 1 place of accuracy.
The work done is 150 joules
Explanation:
Work occurs when a force (F) acts on an object to move it some
distance (d) from the start point
→ Work done = F × d
The S.I unit of work is Joule
A force of 50 N is used to move a footstool 3 m
→ F = 50 N
→ d = 3 m
→ Work done = F × d
Substitute the values of F and d in the rule
→ Work done = 50 × 3 = 150 joules
The work done is 150 joules
