If you have an initial water level in a graduated cylinder of 15 mL and your
1 answer:
Answer:
The answer is
<h2>0.5 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
From the question
mass of aluminum = 2 g
volume = final volume of water - initial volume of water
volume = 19 - 15 = 4
volume = 4 mL
The density of the metal is
We have the final answer as
<h3>0.5 g/mL</h3>Hope this helps you

Answer: The temperature rise is
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed by ice = 5280 J
m = mass of ice = 2.40 kg = 2400 g (1kg=1000g)
c = heat capacity of water =
Initial temperature =
Final temperature =
Change in temperature ,
Putting in the values, we get:
Thus the temperature rise is
