Answer:
382.5J
Explanation:
<em>Use the formula:</em>
E = mcΔθ or Q = mcΔT
m = 100g
c = 0.45 J/g°C
ΔT or Δθ = 110 - 25 = 85°
<em>Sub in the values:</em>
E = 100 × 0.45 × 85
= 382.5J
Answer:
<h2>Volume = 6 cm³</h2>
Explanation:
Density of a substance is given by

From the question
Density = 4.0 g/cm³
mass = 24g
Substitute the values into the above formula and solve for the volume
That's

Divide both sides by 4
v = 6
We have the final answer as
<h3>Volume = 6 cm³</h3>
