Answer:
Q = 360 Joules
Explanation:
specific heat of copper = 0.400 J/g° C
mass of copper = 30 g
initial temperature = 20.0°C
final temperature = 50.0°C
Using the formula:
Q = mcΔT
where;
Q = Heat Energy
Q = (30 × 0.400)(50-20)
Q = 360 Joules

Answer:
<h2>The answer is 2.34 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 7.5 g
volume = 3.2 mL
The density is
We have the final answer as
<h3>2.34 g/mL</h3>
