In which equation does the term "heat" represent heat of fusion?
AleksandrR [38]
Heat of Fusion is defined as the energy required to turn a liquid into a solid, or said phase changing latent heat. In this case the only choice that represents that phase change is (1). Where the heat removed to turn a liquid of a substance into it's solid form is instead added to excite the bonds and liquify it. Yet, heat of fusion (s) ->(l)
is still the same as going from liquid to solid just one is adding and the other is removing, respectively.

Compared to a swimming pool filled with water, a hot cup of coffee has higher temperature, but less thermal energy
Julli [10]
Thermal energy equation is;
    Q = mcΔθ

Q = Thermal energy
m = mass
c = specific heat
Δθ = Temperature difference

the hot cup of coffee has a higher temperature. But the mass of coffee is very low compared to the mass of water in swimming pool. The maximum temperature for coffee only can go up to 100 ⁰C since the boiling point of water is 100 ⁰C. But the mass of water in swimming pool is very large and the thermal enegy is very high compared to the coffee cup due to that reason.
