The answer would be 1,3,1,3
They cancel each other out so they are neutral.
Answer is: 15675 J.
m (H₂O) = 75g - mass.
ΔT (H₂O)<span> = 75</span>°C - 25°C = 50°C -<span> change in temperature.</span>
C (H₂O) = 4,18 J/g·°C - <span>specific heat of water.
</span>Q = m·C·<span>ΔT.
Q- heat (in Joules-J).
</span>Q = 75g · 50°C · 4,18 J/g·°C = 15675J = 15,675 kJ.
Heat transfer<span> is a discipline that study</span><span> exchange, generation, use and conversion of </span>thermal energy<span> (</span>heat<span>) between physical systems.</span>
