Answer:
Final temperature =
Explanation:
Given that,
Heat added, Q = 250 J
Mass, m = 30 g
Initial temperature, T₁ = 22°C
The Specific heat of Cu= 0.387 J/g °C
We know that, heat added due to the change in temperature is given by :
Put all the values,
So, the final temperature is equal to .
Answer:
We have the final answer as
<h2>0.68 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
From the question
mass = 40.8 g
volume = 60 mL
The density is
We have the final answer as
<h3>0.68 g/mL</h3>Hope this helps you
