Answer:
From -15⁰ to 0⁰
H=mc¶
where H= heat absorbed or evolved
m=mass involved
c=specific heat capacity
¶=change in temperature
H=mc¶
Increases exponentially is your correct answer
Answer:
150.8 J
Explanation:
The heat released by the copper wire is given by:

where:
m = 10.0 g is the mass of the wire
Cs = 0.377 j/(g.C) is the specific heat capacity of copper
is the change in temperature of the wire
Substituting into the equation, we find

And the sign is negative because the heat is released by the wire.
